This is a very frustrating symptom. Right at the onset of sleep, I will have an involuntary movement, kind of like a hypnic jerk, but without the falling feeling. This can be as little as my thumb moving, or as big as my whole arm or leg. This does not happen at all during the day. It happens as soon as I transition to sleep. Keeps me up most of the night. Anyone know what causes this and what can help? Thanks.
