diabetic peripheral neuropathy
"I was having such severe pain that I could not get to sleep at all. I went to my doctor in desperation for relief. He prescribed 300mgs of gabapentin three times a day. That did nothing for the pain. I was referred to a pain and rehab clinic where I was given 3600 mgs a day--1200 t.i.d.  That helped much more, but the pain is still not altogether gone. I do physio too, which, in combination with the gabapentin, helps."
