I have been on ritalin for quite a while 50 mgs a day. Now my doctor is trying to put it up to 80mg's a day. I dont think that is a good idea and I think it will make me very anxious. 50mgs a day is good but not cutting it like it used to. So whats the diff between ritalin and dexedrine? which one worked better for you? (i know their differences in the brain but i want peoples experiences)
