Nortriptyline
"I take Nortriptyline 30 mg at bedtime for facial nerve pain brought on by shingles, Post Herpetic Neuralgia.  The medication helps to stop itching, gnawing pain and electrical firing.  The one drawback for me is the constant obsession with food, mostly carbohydrates.  I've gained weight and have negative sexual side effects, but hey,  I'm not in pain.  It would be nice if there was another medication that worked as well as this medication for the pain, but doesn't have the side-effects."
