pain
"I've been using the red capsules for several years with good results.  Recently I was given the beige capsules by amneal and they make me sick and do not reduce my pain.  There were a few white ones mixed in with the others which also worked.  I now have a bottle of beige ones which are worthless unless you want to feel worse.  And, I am unable to get any others because they're controlled and the pharmacy says beige is all they can get from their supplier.."
