I've taken it since November-- 75 mg 2 x a day then 150 mg 2 x a day. For the last 2 weeks; went down to 100 mg 2 x a day--now I'm supposed to go down to 50 mg 2 x a day. I've had so much more pain--I thought it wasn't helping w/ the pain, but?? I'm having nausea and some very bad thoughts... almost started to up it again. I'm so confused. Anyone been in this situation? Help!
