Hello gladtobealive ~ Welcome to NeuroTalk.
I took Neurontin quite a few years ago and I also gained quite a bit of weight but every bit fell off and when I stopped it - thank goodness - and I didn't even diet!!

And - just like razzle said - I took Topamax and weight fell off - too much!! I had to stop taking Topamax and then start it again very slowly to stabilize my weight.

I'm certainly not a doctor and far, far from an expert but I think all the meds can affect all of us in different ways.

Maybe the best thing for you to do is tell your doctor just how things are going and how you feel about Neurontin .... There are other meds to try.

But if Neurontin is HELPING you, maybe the docotr can help you fight the weight gain?

Here's wishing you well -- wishing you the VERY BEST.
And here's a hug
