ShanDoll, I was also put on gabapentin on top of lamictal (200 mg).

Gabapentin was great in the beginning at soothing the agitation/restlessness that I got from a high dose of lamictal. Gabapentin relieved a lot of the physical symptoms of restlessness/anxiety and really helped me sleep.

The best effects (somnolence, anxiety relief) did wear off over time. I was on 1200 mg of gabapentin when the dosage was reduced in favor of another med. But it did help make me physically calmer.

I would definitely recommend it, but if the anxiety comes back, the doctor should up the dosage.

Good luck!
