"for fibromyalgia - this drug did absolutely nothing for me, like taking a placebo pill. no pain relief whatsoever. i was tried on 200mg er. i noticed that after about an hour and a half after taking a dose, i would pass out asleep for about an hour and then wake up not remembering that i even fell asleep. very strange. i&#039;d wake up in full blown pain and i also had stomach cramps which made my pain levels and overall experience much worse. i was so hopeful for this drug because it&#039;s said to treat diabetic neuropathy which i also have in addition to the fibromyalgia but it didn&#039;t do anything at all to relieve my pain. you&#039;d be better off taking tylenol instead of this, that&#039;s how terrible it is."
