Yes--Nortriptyline + Gabapentin (aka Neurontin) is a combination that's been found to be effective against pain, more so than either drug alone! I had been on Nortriptyline alone with some pain relief; neurologist just added low dose of Gabapentin about three weeks ago, and the past two weeks have been my best period since symptoms started in April. I'm not counting on this being a permanent improvement, but I'd recommend this combo to anyone. Here's one of many links to a report on that study: http://www.medscape.com/viewarticle/709766.
