Meprozine and lying on the sofa

I was given this for a root canal. All I can say is stay away from it, ask for lorcet or percocet if you are in pain. This stuff made me feel like i needed to throw up but couldn't. I ended up sticking my finger down my throat at 4am just to get some sleep. All my motor skills were delayed and my balance was off. I was easily startled and agitated. I would be lying on the sofa sleeping and would suddenly get the feeling that someone was standing over me. I woke up and just about jumped off the couch in fright, and of course there was nothing there. Extreme Dry Mouth, and the medication blurred my vision at times. I also had no sense of time and was very disoriented. I also had some of the strangest dreams in my life while on this medication. My right hand would twitch at times, but not very often. This should be labeled as a roofy, not a pain killer.
