"took the pill every six hours for two weeks after shoulder surgery to deal with the immense pain. it worked! then i stopped one day. big mistake. the withdrawal took a week and i felt like going to the er. no one told me to taper off. the pain became unbearable again especially after physical therapy and now i only take one an hour before pt. bottom line, it works but is a narcotic so addiction can happen and withdrawal must be executed carefully."
