"i am currently being treated for lower back pain. i am prescribed up to 4, 5 mg a day of this medicine but only need to take 2 of them a day. until my doctor put me on this i could not get off the couch or do much around my house. now, i can move and with physical therapy, i hope to zap this pain. it works great but does cause me to itch so i take a benadryl with it and it does make me a little foggy. if i don&#039;t eat i do get somewhat nauseated too."
