Don't have a lot of advice on the dysthymia, but be careful with the gabapentin. Not sure what dose you are on, but it higher dosages it can cause severe weight gain. Are you having nerve pain? Is that why the gabapentin was prescribed? If so, talk to him about Tegratol, it works the same as gabapentin and does not have the weight gain side effect. If you start feeling hungry about an hour-2 hours after taking the gabapentin, that is an early warning sign. Hope some of this helps
