chronic pain
"This medication was given to me for fibromyalgia and severe lower back pain. 2 pills every 12 hrs.  A wonderful medication. Lasts 12 hours and doesn't give you highs and lows. It's very smooth. Wonderful for nights because most of the 4 hours meds did not last thru the night and I would wake up.  I love this medication and recommend it to all pain sufferers. I would like them to take out the 325 tynenol."
