I gained 70 pounds in 2-3 months on neurontin. And, I was careful about what I Ate! My final dose was 3800 mg per day. Even at that rate, all it did was make me fat, and dumb. Could not concentrate to do simple math.

Switched to topamax. Never lost the weight, even though topamax is supposed to have side effect of weight loss.

It helped a little. Not really enough to warrant using it.

Now that I am on Medicare part d for meds, I cannot afford it.

Tried Lyrica. It was even worse than neurontin for me. A nightmare.
