GOOGLED MY PROBLEM: HYPNIC JERKS!!

[robzybob]

  Well.... with luck I managed to google my problem and its EXACTLY like my case!!!!!!!! I dont know why I didnt think of doing it in the first place to get to the bottom of this. Here is what it said:

A hypnic or hypnagogic jerk is an involuntary muscle twitch (more generally known as myoclonus or a myoclonic twitch) which often occurs during the transition from wakefulness to sleep (see hypnagogia). It is often described as an electric shock or falling sensation, and can cause movement of the body in bed. Hypnic jerks are completely normal, and are experienced by most people, especially when over-tired or sleeping uncomfortably. The exact cause of the sudden jerks is not clear, but there are hypotheses:

That it is a naturally occurring part of the sleep process, as is slower breathing, and reduced body temperature.
That the feelings associated with relaxation before sleep are misinterpreted by the brain as falling or toppling over, and by reflex the body jerks out the limbs to stay upright.
That in the same way a body will often twitch as a person dies (as a reflex to attempt to keep the body functioning) it is thought the body might misinterpret falling asleep as a situation in which the body needs to be stimulated.
Hypnic jerks are usually felt just once or twice per night. More regular (and usually less dramatic) muscle twitches often occur during normal sleep (perhaps as often as one every thirty seconds). In extreme cases, this may be classified as a disorder called periodic limb movement. The person with the disorder will usually sleep through the events. When a subject is deprived of sleep and is trying to fight sleep, hypnic jerks can occur more often. This normally happens to subjects who have successfully deprived themselves of sleep for longer than 24 hours.

Its annoying for me, (it only happens when I think of it). But last night for example, I was able to sleep without this hypnic jerk. So ya, its off and on, but glad to see its not a serious condition. Hopefully that helps you out too gloomy???? And thanks Rachel for all that interesting info on sleep. Although, my average time of falling asleep is 1-2am, I havent fallen asleep between 9:30-10:30 since I was in highschool
