I also take Neurontin (gabapentin). When I first started taking it, I felt crazy (well, crazier than normal-LOL . But, as my body got used to it, it didn't faze me at all anymore. However, I don't know if it's helping anymore either. I'm on a really low dose (300mg at night), so maybe I need to have the dosage increased. That's one thing on my long list that I want to ask my doctor.
I'm sure (or at least hope) that you can get some info from someone at you doctor's office. Also, you could try calling your pharmacist. I always save those inserts that come with my Rx, and it says that the side effects of gabapentin are: tiredness, drowsiness, dizziness, tremor, back pain, dry mouth, constipation, increased appetite, or an upset stomach. It also says that if you have these severe side effects, you should check with your doc ASAP: decreased coordination, double or blurred vision, back & forth eye movements, flu-like symptoms, persistent sore throat or fever, swelling of ankles, memory loss, or trouble speaking. Also, if you experience mental or mood changes, or suicidal thoughts, contact you doc immediately. (This is all info from Walgreens, BTW).
OK, I don't know if this info helped, but I still think you could call your pharmacist for further info. I hope I helped a little. Good luck!
PS-I totally wrote this before reading Karen's (getting by) post. So, I guess I could have just typed, "Yeah, what she said." LOL

Vicodin, Neurontin, Ibuprofen for pain-which doesn't help, BTW
Zoloft & methadone (NOT for pain) for sanity-which doesn't help, BTW
Klonopin for anxiety (Guess what? Doesn't help!)
