My doc wanted to put me on Elavil for migraine pain and I declined due to the weight gain issues. At one point I did try Neurontin and did gain much weight and dumped it fast. I ended up taking a small amount of Desipramine for my migraine issues and gained about three or four pounds I think...that was it. The Despramine is very similar to Elavil. I have found keeping my meds low and combining them with natural products, vitamins, good food, good living and moderate exercise gave me better results than medication alone. Now, I pay close attention to supplements, etc. I am fortunate to go to a physician who is open minded about these things. You can get much information at the library. Sometimes an experienced salesperson at the health food store can provide insight. It requires much patience. Wishing you well.
