peripheral neuropathy
"I was recovering from alcoholism and I couldn't sleep because of inexplicable pain in my legs. I may have been masking the pain by drinking before I decided to quit. In any event, the pain was driving me crazy and after 3 months I relapsed just so I could sleep. Finally my doctor prescribed Neurontin and the pain was gone. I slept soundly and now I haven't had drink in 5 years. So you could say Neurontin saved my life."
