Hi all, I also have SFN, diagnosed in January. Went up to 2700 mg of gabapentin, and had no perceptible pain relief but was wiped out. My neuro told me to take one pill away at a time every 3 days until off completely. Then worked my way up to 3 x100mg lyrica per day. Just got to this level, so can't say yet, but seems a bit better. I have actually lost weight through this whole experience, which came out of the blue in October, and seem to have no appetite. Doc thinks it may be the autonomic stuff impacting my stomache and digestion. Anyway, I know others who are pretty happy with lyrica so we'll see
