"i did not have a good experience with this medication. i was taking vicodin for chronic low back pain from an injury 4 months ago. i wanted to try something different to see if i could have less side effects than vicodin. i waited for a weekend when i knew i&#039;d be staying at home and i&#039;m glad i did. i took 50 mg at 1pm and it did not help with the pain at all, so i took a 2nd (as advised  by my doctor) at 4pm. i felt tired when i sat down, but energized if i kept moving around. it definitely suppressed my appetite for the rest of the day, which that part is fine. by the end of all of it, i was itching like crazy, felt very tired, and the pain had not been managed at all. i&#039;ll stick with vicodin for now.
