"for me, this worked great as pain relief for a herniated disc. i found the pain to be less agonizing throughout the day, and i could do things that i needed to (cleaning, vacuuming, grocery shopping, carrying the groceries, etc.).  the problem that i had with the medication is that i had horrible memory loss.  i am a full-time student and could not handle the problems i had trying to retain hard information.  my doctor tried to combat this by putting me on ritalin but then i couldn&#039;t sleep.  i have had to go off of pain relievers for this exact problem."
