My Adventures Without Coffee

Anyone who reads my books can probably guess that I love my coffee. Daniel the vampire astronomer cannot imagine being undead without coffee to warm the blood he consumes. Where would Ramon be without Fatemeh’s strong coffee to prime him for adventures in the wild west? Even my spacefaring adventurers make sure their ships are stocked with coffee.

As for me, I started drinking coffee during my senior year of college. I had housemates who made coffee, plus that was the year I worked at the Very Large Array radio telescope. Out there, the beverage choice was soda you could pay for or free coffee. As a college student, you can bet I took the free coffee. I hardly lived a caffeine-free existence before that. My mom always kept a pitcher of iced tea available. As a kid, if I wanted something to drink, it would be iced tea. As an almost nightly treat, she would let me have a Pepsi while I watched TV.

A few weeks ago, my doctor noted that I have an oddball heart rhythm. This is nothing new.  It was first diagnosed when I was in my 20s and as far as I knew, that was the way my heart rhythm has always been. Cardiologists have told me there’s little chance of it developing into anything worse. Despite that, my general practitioner was a bit worried. He immediately asked about my coffee consumption, and I told him I was a coffee drinker. He suggested I might want to give it up to see if it affected the heart rhythm. Given that the men in my family have a history of heart disease, I decided I should give it a shot and see what happened.

So, starting just before mid-November, I stopped drinking coffee. I also avoided caffeinated sodas and tea. I know I did consume some caffeine in chocolate and even in the occasional cup of green tea, but by my estimate, my caffeine consumption was the lowest it had been since I was a very small child. The first week without coffee wasn’t easy. The first day, I had a migraine-like headache. After that, I developed muscle aches in various parts of my body—my arms, back, legs, and hips all hurt at one time or another. This isn’t surprising given that caffeine does act as a vasodilator and giving it up would mean at least slight constriction of blood vessels. Despite that, I found I didn’t miss the coffee as much as I thought I would. It didn’t take me that much longer to “wake up” in the morning without it than it did with it. I really missed it on weekend mornings when I was most used to taking some leisurely time to read before starting my day. Also, after that first week, the pain finally vanished.

I didn’t get grumpy during my break from caffeine, but I did find myself feeling a little more prone to giving into my introvert tendencies and withdrawing to myself, especially during the first week when I was dealing with the pain. It’s hard to say whether this was a direct effect of stopping caffeine, or a side effect of the pain.

During this period, I looked into the effects of caffeine and learned that there, in fact, is little correlation between stopping caffeine use and correcting heart rhythm. Despite that, I personally have felt that I probably consumed a bit too much coffee on occasion and it seemed like it would be easier to return to moderate consumption if I started from “ground zero” so to speak. Sure enough, when I returned to my doctor this past week, he noticed essentially no change to my heart rhythm. I celebrated with a cup of coffee. Still, as I say, I hope this will be a first step in using a little more moderation in my coffee consumption.

Periodically a news story will come out about caffeine research. Sometimes the research indicates problems. Other times it indicates benefits. Most of it seems to agree caffeine, like most things in life, is best if done in moderation. Of course, any changes you make should be done in consultation with your doctor. I’m just a guy who tells thrilling tales of the imagination and studies distant galaxies, stars, and planets. Still, I found it empowering to know that I could give up caffeine with no problems if I desired.

Warning Signs

In last week’s posts I discussed reading for the Nebulas and the reality of my “day” job operating telescopes vs the perception. In point of fact, operating telescopes involves a lot of time sitting at computers and reading is also a job usually done sitting, unless you want to walk into objects and people. Of course, I also write, which is another activity that involves sitting at the computer. This is pretty typical of what I look like at work:

This may sound like I’ve set myself up to be quite sedentary, but, I do move around quite a bit and I like to take long walks. In fact, my normal daily walk when I’m at home is usually right around four miles. In short I’m not in terrible shape for my age and I walk often enough that I’ve experienced more than my fair share of leg cramps when I haven’t properly hydrated or stretched beforehand.

Last week, around day four of my shift, I started experiencing some terrible leg cramping. The only weird part is that I hadn’t been walking much for the past few days. Mostly I’d been sitting at the computer and working on a project and doing some reading for breaks. Normally, I find that leg cramps subside very quickly. I stand up, walk around a bit and they settle down. This wasn’t like that. Instead, the cramp just kept getting worse for about 24 hours. After that, it started subsiding, but very slowly.

Checking the Internet, I scared myself reading about the dangers of deep vein thrombosis, which is when a blood clot forms in your leg, which can then break loose and travel into the brain, heart, or lungs. In some cases, these things are known to kill people. However, my impression from the reading I’d done was that deep vein thrombosis doesn’t get better. The fact that my pain got better led me to believe it really was a nasty muscle cramp.

Also, I grew up with parents who might be described as hypochondria-phobic. As a kid, if I complained about pain, they usually told me I was imagining it and to “tough it out.” For me, the result is that I have a hard time admitting to pain even to myself. Sometimes I even have a difficult time distinguishing between levels of pain. So, I was already prone to tough it out and follow up later if it didn’t get better.

By the time I got home, the cramp was mostly gone, but I still had a persistent knot in the back of my leg. I assumed this was the muscle that cramped up and gave me problems. When the knot hadn’t gone away, my wife and I decided I’d better see the doctor. I figured he’d tell me it was a cramped muscle and there was little he could do for me. At which point, I’d make an appointment with a good masseuse.

The doctor took a look at my leg, pointed out it was swollen and sent me off for an ultrasound. Sure enough, the diagnosis was thrombosis. Fortunately, it wasn’t in the deep vein that’s the most serious, but my doctor pointed out that it’s a warning sign. He’s helping me take measures to deal with the current clot and to help me minimize the chance for new ones.

In a very real way, this is a first-world problem. It’s a medical issue caused by work that demands I sit too much. There are a lot of people around the world that would look at me and wish they had my problems! That said, this is a case where I should have listened to my body. I really should have called in sick to have this checked out right away instead of trying to tough it out. It’s frightening how serious this could have been.

Despite this unexpected excitement, I’m pleased to report that I haven’t fallen behind on Owl Riders, book four of the Clockwork Legion. I didn’t get ahead as I hoped I would this week, but I’m making good progress. I’m also doing my best to take breaks, and get up and walk around, so this doesn’t happen again!

For those who want to catch up with the first books in the series, you can check out the Clockwork Legion series at: http://www.davidleesummers.com/books.html#clockwork_legion

All the books are available in ebook and print, plus Owl Dance is available as an audio book, and Lightning Wolves is in the final stages of audio production.

On Turning 50

Over the weekend, while at TusCon in Tucson, Arizona, I celebrated my fiftieth birthday. It’s one of those points in life where I find myself looking back to see where I’ve been as well as looking forward to see where I’m going.

In my first fifty years, I’ve written and published nine novels, eighty-four short stories, and fifty-four poems. I’ve edited three anthologies, plus two magazines for ten years each. I contributed to the commissioning of the WIYN 3.5-meter telescope and the NMSU 1-meter telescope. I’m co-discoverer of two variable stars and I helped take data that contributed to the discovery of dark energy. Most of all, I’m proud to be the father of two incredible young ladies, one in high school, the other in college, who have a wide range of talents in such areas as computer science and mathematics.

Looking ahead, my tenth novel, The Astronomer’s Crypt, is nearing release. I have two anthologies in the publication queue: Kepler’s Cowboys and Maximum Velocity: The Best of the Full-Throttle Space Tales. I have four short stories accepted and awaiting publication. Beyond that, I’m in the early phases of writing a new novel and I have a “fix-up” novel a little over half completed. Plus I have story treatments for four more novels. Presuming no major funding shifts, I expect to be involved in commissioning two new instruments at Kitt Peak in the coming years.

As I reach fifty, I’m arguably in the best health I ever have been. The arthritis that plagued me for years is in remission and I regularly take long walks through my neighborhood. Nevertheless, one specter looms over me. My dad was only fifty-two when he died suddenly of a heart attack. In the plus column, my doctor is helping me watch my heart health and both of my brothers have now outlived my dad by over a decade. I have no immediate reason to fear for my imminent demise. Nevertheless, I find myself grieving for how truly short my dad’s life was cut and watching my health has taken on a new urgency.

In short, as I turn fifty, I feel proud of what I’ve accomplished. My regrets are minimal. While there are some harsh words and rash actions I’d take back if I could and some friends I’ve lost touch with over the years, it’s hard to say I’d have a better life if I’d taken a different path. I have several exciting things to look forward to in the coming months and years, plus plans and goals for the years beyond that.

Thanks to my readers for sharing some of this fifty-year journey with me. I look forward to sharing the coming years with you as well.
