I've taken it since June to help with my LFT's which were off I think due to drug toxicity--I think Stattera which I took to help with my functioning was the culprit.

I heard that you had to be up at a 1200 mg a day to have the equivalent pain relief of a celebrex for musculoskeletal symptoms. ----and it takes about a month to start getting relief.

I did get significant pain relief and my liver function tests dramatically improved. I really can't tell how much, if at all it affected my neurapathic issues.

Unfortunately, at that dose I also developed severe insomnia and urinary frequency. I also became so anxious that I was bouncing off the walls.
As a result I discontinued it. I may try again at 200mg.
