I've been on paxil and elavil for 18 years. A year and a half ago I had a sharp pain in the right side of my head that turned into horrific head pain/facial spasms. I was put on 900 3 times daily mgs neurontin, it was the only thing that stopped the pain. Then I got a night bite, I wear to keep my teeth from grinding, I'm down to 100 mgs once a day. Now I'm taking it every other day and hope eventually to go completely off it. Angie
