Hi dottie, When I first started the Elavil it was 10mg twice a day. That did well controlling my pain, but I was unsafe to drive and work. So he's had me down to 10mg at night now. It works fairly well with the pain, but doesn't last all day. Thought about doing 5mg twice a day and seeing if that helped any. Just worried it wouldn't take care of the pain as well. And no antihistamines, on enough meds.
