For those exploring Gabapentin, I will just add a bit of my experience with this medication in the hope that it might be helpful. Once my SFN was diagnosed, I began using Gabapentin for pain relief from the "needles" that ravaged my hands, wrists and lower arms with pain. After the first 6 months as my condition progressed, more of the medication was prescribed for night time to go along with the lidocaine based topical compound LPKA which works to take the edge off the pain as I prepare for sleep. So after experimentation, this is what works for me at this stage -- 300 mg in the a.m. and 900 mg one hour before bedtime. That allows me to drift off pretty easily and sleep well until the electrical pain zappers start at dawn. One day I got the dosages mixed up and took the 900 mg in the morning. And now I know why it works......although my pain was significantly reduced, I became a bit fuzzy and was struggling to remember things until it wore off. That's o.k. for night time but can be disconcerting during the day. I don't think I would want to be taking it 4 times a day. I will be meeting with my neurologist this month to discuss my future needs and options as the SFN has appeared to have added pain to the numbness in my feet. I also know that my partner has taken it for Restless Leg and it is also prescribed for dogs with a nerve condition called Syringomyelia (SM). So just because the medication was developed for seizures, doesn't mean that it won't work for other nerve related disorders. So it may be that each of us has different needs, different experiences, and different tolerances. There are no easy answers or road maps for this journey.....just lots of challenges and the will to cope with them as best we can.
