Thank you. That is helpful information. I'm at only 200 mg. The only problem I have with Neurontin (Gabapentin) is that it definitely makes me drowsy even at a low dose. I know when it's near time to take it again, too, though, because the nerve pain starts nagging me. Thankfully, I never get the horrendous rash that people talk about. I'm thinking it's because I only had three pox when I had chicken pox as a baby, according to what my mother told me. Yeah, I do get that stabbing pain. It likes to get me under the left scapula. I would liken this stabbing pain to someone driving a long sharp needle into the places with the worst pain. Then, of course, there are the crawly feelings that make one itch. And, some of it feels like it burns. I am thankful childhood chicken pox was as mild as I describe, because I am sure that the nerve pain would be worse like yours must be. What I have been experiencing is bad enough. Now I know that if this doesn't feel better soon with the 200 mg dose every 6 hours that I can ask for a higher dose if I need to. I am pretty sure that 600 mg is still considered to be relatively low. I can't forget to take this stuff either, because right about the time I'm supposed to take it, I start feeling the nerve pain. Speaking of which, I have to go take the dose I am prescribed.
