I've taken Neurontin (the generic is gabapentin). They start you at a small dose, then work you up to a higher dose. It was an attempt by my neurologist to control what they thought was nerve pain in my legs and then tingling feeling I have in my hands and feet. It made me feel a little drunk at first, but then I got more used to it, and it wasn't that big of a deal. Unfortunately, it didn't do anything for my pain or tingling, so I stopped taking it.
One important thing to remember with Neurontin is if you're on it and want to stop, you should notify your doctor so she can wean you slowly. If you stop it suddenly, it can cause a seizure.
I think it might be worth a try for you-- just start with a small dose, and see how it affects you.
