It was the first drug I was started on for my symptoms. It helped me get some rest. My SFN ramped up and was all over. I maxed out on it, so then Lyrica. Taken off Lyrica. Now on Amitriptyline 50 mg.
Good luck and hope you get some relief soon.

A while back I took Gabapentin for a few years, then discontinued it which was no fun (you need to withdraw very slowly).

When I started having twitching & cramping, I agreed to go back on, and it controlled those symptoms well.

All of that was before I started to develop significant nerve pain, so I don't really know if it's currently doing anything for me as far as the nerve pain.

Side effects for me are sedation (which may be a good thing for you if your having trouble sleeping), memory problems (particularly searching for a word or name you want to say but can't remember it), weight gain, and some loss of libido.

Thanks ragtop262

Why did u discontinue? Do u think it's helping ur pain at all? How long have u been on it? What dosage?

When I was on it the first time, it was actually an off-label use for controlling anxiety (I couldn't tolerate most of the usual medications they use for anxiety issues). Eventually, I decided that the side effects were not worth the limited benefit I was getting from the drug, so I discontinued. At that time, I think I was taking 1600 mg/day (400 x 4). I tapered down from 4 to 3 to 2 to 1 capsule per day pretty easily. But it was hard to get down to 0 - I had to open the capsules and make my own dosages to bring it down in very small increments.

Currently, I'm on 1800 mg/day. (600 x 3) My neuro suggested going as high as 3600/day, but I don't really want to go any higher if I don't have to. I'm OK with the level of side effects I have now, but don't want them to get any worse, as they surely would at a higher dose. I've currently been on it since last fall. I started taking it before the neuropathic pain started, so I honestly don't know if it's doing anything for the pain or not.

I'm sure you've already figured it out, but none of these medications are magic pills - they all come with side effects. Each of us has to evaluate the symptoms we have, and what level of side effects we are willing to endure to get an improvement in the symptoms of our disease.
