I've just had my Neurontin doubled again, 1,200 MG 3xday. I've noticed no difference since I've started taking it. Does it help anyone else? It's pretty expensive (80 dollars for 180 of 600 mg after insurance). I've been on it for 6 months, no improvements. I've been tested now for Heavy Metals and 12 hour fasting glucose for the 2nd time and both are within normal limits
