My doc put me back on elavil for pain when I relapsed a few months ago. The first night I took a whole 25mg pill, not remembering that the first time he put me on it I was catatonic the next day and had to use a half for a week, I did have a lot less pain the next day, as I did the first time. And the nurse said then she was surprised that it worked that fast, but I know it was not my imagination because I had forgotten it (of course) by the next round and the same thing happened. Well, this past week I have been PMSing and in a lot more pain than usual. So night before last, I upped what I took to 1 1/2 since I had plenty left from the first month when I took 1/2 for several weeks. I did seem to be better yesterday and I managed with 2 rounds of Alka Seltzer and 1/2 of a pain pill with 4 advil. I want to know how much you take and if you think it helps with pain. Once PMS is over, if I don't go back to "normal" (whatever that is! ) I am thinking of asking my doc to up my dosage. Thankfully it does not make me crave sweets.
