That's a nightmare, I am sorry you are in this position. Is the doctor you spoke to your psychiatrist or GP? If the latter, then maybe you could get in touch with your pdoc with their more specialised knowledge? I started taken bupropion (wellbutrin) while still on amitriptyline - that combination made seizures more likely but I was fine. I do really feel for you as lack of sleep has been a major part of depression for me and it has helped having had decent sleep this year. I was still very nervous about decreasing the amitriptyline as I really didn't want to give up just being able to sleep most nights. Take care of yourself.
