Jerking While Trying to Sleep
Now that I got your attention... lol.
Lately, right at the point I start to drop off to sleep, I will get a muscle twitch, or jerk, in one or the other of my arms. Sometimes they can be pretty severe. Even the minor ones will bring me back to full conscience at least for a minute or two before nodding off again. Does this indicate I am overwhelming my CNS from too much physical activity? This happened to me once before a long time ago for a few nights. That time is was so bad I could not sleep at night at all. After a few days it passed and has only started up again along with my activity level. This time it is not nearly as severe, just annoying.
I bike 15-20 miles 6 days a week and lift 3 times a week. Before this I was a professional couch potato for years and years...
