Sorry to hear that newstown. As you know I have a very similar episode lately. I'm glad to say the amitryptiline seems to work as I am now on 1/3rd of the tramadol dose I was on, yet am feeling less pain. I hope to get off completely and only take ami for a while so that the tramadol will become effective again.
BTW I don't think your short flirtation with alcohol last year has any effect today. PN just seems to have a mind of its own. I'd suggest to keep on trying different things to see what gives you the best quality of life. I know that's not very useful, but it's the best I can do.
PS: I'm on 1234 - not the musical countdown, but number of days sober.

Despite the PN setback I'm still feeling very comfortable living without alcohol, and see no reason to change that anytime soon.
