Nuerotin has helped a lot of people, but it can have side effects. My Dr. put me on it for a while as part of a cocktail for migraine pain. It worked more like an anethesia than analgesic for me. I'd take it, never feel drowsy, but would wake up in my chair, still sitting with my upper body completely bent over and my head on the floor. My friends told me that I slurred words, used words in conversation that made absolutely no sense.
If you are having bothersome side effects, your Dr. needs to know. There may be a better option for you. You need rest, and if its keeping you up at night, it will catch up to you.
This is a drug that you don't want to just stop abruptly. If you continue taking the drug and its benefits outweigh the side effects, when its time to stop taking it, ask about a taper.
