restless legs syndrome
"I am in my late 20's and have had restless legs since my late teens.  I have been on Gabapentin now for about 2.5 years and it has been wonderful.  RLS stopped almost immediately (to my memory).  For whatever reason, the RLS comes back periodically and I have to tweak the dosage a bit.  At first I increased (at the doc's request) but soon reached my 1800 maximum dosage, 600mg 3x day.  When symptoms popped up again I stopped taking the GP all together; believing that it had stopped working.  Later in desperation, I took some leftover GP and it worked again.  Now I try to stay at a low 300mg dose and take another 300-600 if I feel that familiar RLS itch as I’m settling in."
