If you are lacking magnesium, calicium or potassium you may have muscle spasms.
Debaser is right about remaining well hydrated also.
Hope your EEG goes well.
I have Restless Leg Syndrome and don't know if this is what you might have, but my legs jerk around all the time...day or night...especailly when I am laying down or sitting...or tired. They have a painless, crawling/tingling sensation along with the jerking which I wouldn't describe as a spasm. It's just like they have a mind of their own. Can't sleep in the bed with the hubby anymore...I've kicked him in places that made him see Elvis! If this is what you have, it is very benign...just annoying.
