chronic pain
"If I could rate this medication as a ZER, I would.  Virtually no pain relief, only nausea, intermit diarrhea, headaches and vertigo.  It does NOT sick to the inside of your cheek, as everytime you swallow it moves around and either sticks to your teeth or you swallow it. Horrible, horrible medication. Films often crack in half by the time you can finally pry them out of the foil and they are so small that if you have an sort of tremor, as I do, they often fall out of my fingers. IMO, they need to scrap the whole thing and start over. Horrible."
