i take 300 4 times a day and then my dr increased it to 400 4 times a day. for it to be effective some people take 3000 mgrs a day. it makes me too sleepy. i stopped taking it and now my pain is way up. i didnt tell my doctor i stopped i just told him my pain was way up. now im going to have to go on it again...i was taking caffine pills to stay awake and they barely helped. now i dont want to have to go back on it but i may not have a choice
