What can trigger primitive reflexes in adults? I took 20mg oxycontin and woke up sucking involuntarily?

Question

No lectures on drug use, please -- I know it's risky, I take full responsibility for my actions, and understand what I'm doing to myself. I like to experiment. Anyway:

Last night, I crushed up a total of 20mg oxycontin. I took half orally and insufflated the rest an hour later. I'm opiate naive, so I have no tolerance to it built up. I started coming down about two hours after taking it, and fell asleep two hours after that (so I fell asleep four hours after taking the oxy).

I woke up three hours later (seven hours after taking it), feeling alert and awake. I didn't get up though, just stayed there laying in bed, and noticed that I was having a sort of involuntary sucking response. I'd suck with my mouth closed a few times, then stop, then it would start again. I wasn't alarmed by it, as the action was soothing, as if I were a baby again; but I'm a little curious as to what could have caused it, or if anyone else has ever experienced this type of reaction.

Answer 1

Oxycontin can't be the culprit.

The only drugs that precipitate "tardive dyskinesia" (involuntary tics and primitive movements due to alteration of the extrapyramidal system) are anti-psychotics.

20mg of oxycontin is a pretty hefty dose; be careful, as that stuff can stop your breathing.

Answer 2

No long explicative necessary here. Drugs alter your brain, so I am sure your "sucking" was probably your body's response to the drugs frying some of your brain cells....Or better yet, it was a hint from God that if you continue down this "experimental path", you'll end up in a baby-like vegetative state. My advice - leave the drugs alone!
