Why the fuck do people like promethazine? It's a phenothiazine, if you think it's fun you'd probably love Thorazine. Nothing like shuffling around like an over medicated schizophrenic.
Holy shit no. No fun. No fun at all. Anything in the major tranq family with a side effect of tardive dyskinesia is NO FUN, no matter how much fun you had before that moment. That shit is PERMANENT if not treated immediately with benadryl. And it really isn't that much fun, it damps down the emotions and barely has any euphoria (probably placebo since your standard demons are damped down).

I spent a weekend with my tongue flipped (on it's own), my jaw grinding (on it's own, EVEN when I consciously attempted to stop), and the emergency doctors at the 1st hospital fucked me up even more. It felt like a strong guy was standing there, holding my jaw with both hands, and was forcefully rotating it, pushing hard in all directions. The more I fought, the worse it got. My legs would have gone next. A couple more days without benadryl (IV at the 2nd hospital) and it would be PERMANENT.
Probably the scariest moment in my life was when the benadryl script (yes children, benadryl was prescription only when the dinosaurs rules the earth) ran out and I waited to see if the symptoms started coming back. Scarier than forgetting to breathe for a few minutes at a concert. Really. I'd rather be dead than shuffling around the rest of my life.
And once you are sensitized, anything in that family (compazine for nausea) in the smallest amounts can trigger it.
Not recommended.
