I agree with Mrs. D that you probably should have been tapered off the Amrix. If your Dr intended the new drug to compensate it sure isn't working. Be careful stopping the new drug abruptly too, not knowing what it is I don't know if that will be a problem but it could. I think you need to call the Dr right away, go to the ER, talk to a nurse, or something. I have no idea if it is a dangerous reaction but it is sure something you shouldn't have to put up with. I was once given too much codeine and hallucinated the monster from the 'Alien' movie.
