Opiates and Body Jerks??

[Entersangeman]

I was wondering if anyone had any input on these full body night jerks i am having. The medical term for what im expierencing is termed myoclonus. It is a sudden, and uncontrollable jerking of the limbs or body. I expierence this whenever i try to fall asleep on a plane or in a car. It seems anytime i take an opiate, in my case Oxycodone (percocet/roxicet), shortly before i lay down or try and fall asleep i experience these violent jerks. Id be  laying down relaxing and all of a sudden my leg kicks, and recently my whole body just jumped. These jerks are very scary and only happen when i take an opiate. Does anyone else experience what im expaining? What causes it? What does it mean?  Also, during the same time ( usually end of the night right before i try to fall asleep) I expierence sensitivity to sounds..If my phone rings, or a loud commercial comes on i jump. Feels like someone suddenly yells in my ear? Finally, when i close my eyes, and move my eyes around while they are closed i get this odd feeling. The feeling is very hard to explain, its not painful, and it almost feels good? This stuff is confusing and scaring the **** out of me! Please let me know if anyone hase experienced anything similar!

Thanks!

I thought I was the only one that had these. It is a reation to the opoiates, Its werid to explain but its kinda like a sppedball works. start falling asleep and right before you hit the first stage of sleep, BAM it hit you. Sound famair? Im on Methadone 360mgs a day, for 3 years now, It took my body to adujust almost 2 years. I found out i should have seen a dr though, It could be very unlikly but it can be early seizures. Are you on the med for a reason are are you hooked? Be sade and see your dr, if you dont want to see your dr then go to the Er tell them you dont have a dr,so they wont call him. They willl ask where and why you are 0n the pills, nice thing about ER you can spew anything.
