From your other posts, it appears that you are only taking 300 mg/day. For Gabapentin, that's really a low dosage. I titrated up to 900 mg/day in the first few days and got partial relief from twitching/cramping. Then I stepped it up to 1800 mg/day after about a month, and got much better relief.

From what I've read, 1800 mg/day is a typical dosage for treating cramping or pain. My neuro said I could go as high as 3600 mg/day - but I think side effects would be too high for me at that dose.

So, you have just started and are at a low dose. The fact that it seems to be dulling things is a good sign that its starting to work. Give it time and don't be afraid to move to a higher dose.

Gabapentin does have side effects, but for me they aren't nearly as bad as the various antidepressants I have tried.
