"i had surgery about 4 years ago on my ankle, and have had nerve damage since then.  i was diagnosed with complex regional pain syndrome recently and put on gabapentin for it, my nerve pain is gone, and as a side effect my sleep has returned to normal.  i have found that if i don&#039;t take it with some sort of food, that it makes me pretty non-functional.  all in all i would say this has done wonders for my pain, and i use tramadol for the break through pain.  i have lived with pain for years, and this made me pain free in about 4 days time.  wonderful drug.  i was on 300mg/day for the first 3 days, taken at bed time, then went to 600mg/day taken at bed time.  no negative side effects, just ones that are actually positive."
