you have to wean off caffeine.. unless they gave you meds to counter the withdrawal.. I mean, IT'S A DRUG!!! But I'm glad to hear you are going to begin eating right. The garbage those fast food places serve will kill the whole human race, imo. I can't eat any of it, as there's no fat buffers in my intestines, and when that stuff hits, it's instant distress and rejection! (I eat lots of clean salads that keep my insides clean from fat.)

Good wishes... it is a good thing. though the going might not feel like it at first!
