"three years ago, after a hospitalization for a severe ischemic colitis episode, i had severe and unremitting nerve pain. i tried gabapentin which did work initially. after about 6 months, the pain gradually returned. i then was put on 10 mg of nortriptyline, which was like a miracle, no more pain. i take it at night and have no residual effects the next day. i wish i had tried it sooner!"
