Like HereKitty, I take Neurontin 300 mg during the day and 600 mg at night. 600 mg does make me sleepy but hey, it's bedtime anyhow. I have been taking it for years and for my neuropathic pain, it has become my best friend. I cannot imagine what things would be like for me if I didn't take it.
Dr did add Lyrica at one point but that didn't work for me.
Word of caution and from experience - don't put ice on it.

I tried that once during a flare and it made the pain worse. Lesson learned the hard way for me.
