Started on the full dose last night after a week of taking a half-dose. It hasn't completely removed the leg pain, but it has blunted it noticeably. I'm very pleased to say that the brain-fog effects of the Gabapentin are gone. Not only am I back to what passes for normal in my thought processes, I'm much more energetic and alert. I didn't realize just how very groggy the Gabapentin was making me until I was off of it and could feel the difference. I spent the six weeks I was on that stuff constantly exhausted and just on the edge of passing out — which is no doubt why I was slurring my speech, dropping stuff, and being generally brain-dead.
So thank goodness that's over! Definitely on the right track.
