I think that's something you need to discuss with your doctor. Being as these kinds of drugs work so differently for each person there is no optimal dose as far as that goes. It's a hit and miss situation. You may have to have your doctor just up the dose and see what happens.

I have to say this: Every time I see that someone is taking Neurontin I shudder. Neurontin, for me, made my pain worse the longer I was on it so the dose was increased. Oh, it worked fine at first. But after a few months the dose had to be increased. I was getting to the point of needing *another* increase when I stopped taking it. Most likely related to causing B12 deficiency. It also caused weight gain and bloating as well as suicidal depression for me. I'll never take it again.
