Greetings ! Well you see Duromine is used for suppressing appetite in those who are overweight due to excessive food intake but you seem to be suffering from some type of obsession for food which is making you to eat food as long as you start vomiting, also this could also be attributed to a condition called as Bulimia Nervosa where in after taking too much food there is a sense of extreme guilt and frustration which makes the person to induce vomiting. So it is unlikely that your doctor will prescribe you duromine which has it s use quite well defined but now that you are armed with two plausible differential diagnoses you shall discuss the same with your doctor and ask him to start you on an anti depressant drug like prozac which will work effectively in your case irrespective which of the two diagnosis you end up with since it works in both the diagnoses. I hope this helps. Regards
