Doesn't work all that well for pain. Causes side effects like itching, constiaption, weight loss, and messes up your mood! Lost weight on this and lowers your seizure threshold. Has interactions with just about every medicine there is! Hate it! Manufactured to be "non addicting" but that's BULL SH*T! This is terribly addicting and withdrawls are a bitc*! Deffinately do not reccommend this!
