I started Gabapentin over a week and a half ago. I am on 100:200:300 starting today. So far, it's helping more than the nortriptyline with everything other than the burning and stinging. Gabapentin is helping those symptoms a bit, I just think nortriptyline did a better job with those symptoms. The good thing is it's really helping me sleep! I sleep a solid 4-5 hours a night. I wake up on and off after that but I am able to GO BACK TO SLEEP! which did not happen before. So, if Gabapentin does nothing more than help with my sleep then I will consider it helpful and keep searching for a med that I can add, that will stop the throbbing, pulsing, burning, and stinging a bit better. I know I am not on the full dosage yet, I am hoping these symptoms will improve with a higher dose. The other good news is that my blurry vision has improved quite a bit since dropping down to 10mg of nortriptyline.
