About 6 months ago I had a reaction to some medication - a seizure of some sort - first one i'd ever had. Afterwards every now and then as I would be falling asleep my body would shake or vibrate a little bit. Now - a couple of nights each month when she notices, my wife will wake me up and say that i'm shaking - my whole body. I don't seem to notice that i'm shaking in my sleep (no dreams about shaking) and i'm not hard to wake up. I don't have any difficulty going back to sleep and i'm normally not tired the next day. My wife says its something I do quite frequently during the night though. I don't think I have any type of day tremor or anything like that. Anyone have any suggestions? I would really appreciate it as this is something that is worrying me greatly.
