In January, I tried to hit the trainer every day for at least 30min, to get ready for summer. Febuary, I got hit with a couple of colds, and spent a fair amount of time outside shoveling, and haven't spent very much time on the trainer at all. But I noticed that a couple of problems, and I think it may be low electrolytes.
I've got a tic in my lower eyelid on one eye. I had that for a while in college (actually, I was commuting by bike at that time) but I figured it was from stress. I also get a heart palpitation (? feels like an extra beat) every once in a while, although a couple of times it felt more prolonged (probably from thinking about it). Last summer, and with recent trainer rides, I found that I very often had an abdominal cramp shortly after getting off the bike (but last summer I didn't have a tic nor this heart thing).
It's not as if I eat poorly; I usually have a banana/day, tend to eat a PB&J sandwich on light wheet each day with yougurt, and cereal for breakfast (along with some other fruits and who knows what for dinner). I'm tempted to try having some sports drinks to see if this allieves symptoms; but I actually haven't been active this week, so I don't know why I'd be having a tic in the first place. I'd guess my water consumption at 1-2 quarts/day. I did switch my lunchtime and afternoon coffee break to green tea instead of, well, coffee.
I do have a physical at the end of the month, and do plan to bring this up. I'm just curious if I should try some "fixes" before going. [I'm a sedentary 31 BTW.] I'd hate to have those fixes hid any real problems.
