So emberaasing enough, I'll say I've been on opiates for probobly 3 years whether it be hydro, oxy, or subs. Recently I've gotten a pretty high dosage (about 250-300mg) going lately on oxy's. I've got a problem that I've always had to some extent, but recently, it has gotten much worse: I'll just jerk all-the-sudden. Out of the blue, I will have a panick feeling and then I'll jerk like I'm falling. This is an uncontrollable thing, so I'm hoping this isn't a precurser of something bad.
