I'm up to 2400 a day. I see my pain dr Thursday and I'm going to ask him the best way to quit taking. I've been on it for a couple of years and whenever I say it doesn't work, they up the dosage.
Personally, I just get the side effects without the relief. The side effects are grogginess and a general tired, almost lazy feeling. I think everyone on this board has tried it.
It must work for someone.
