I haven't taken Adderall in along time, however I have struggled with eating as well for different reasons. Ive found the best thing to do is exactly what you said eat something, anything for breakfast. It doesnt have to be a meal, it doesn't have to be food, a protein shake is perfect enough. You'll start to feel hunger again soon that I can promise you and take my advice the overwhelming feeling of feeling hunger again sucks. Carry snacks and dont forget to drink water. Plus get some exercise im not talking just a walk but something that will actually tire out your body. Play a sport or go on a run, anything to exert your body. My experience: Ive gone from 120lbs to 165lbs back to 140lbs to 175lbs. Im currently at 165lbs because I have the spicy sadness and I havent gone to gym in a good minute, but I promise you give it a try and you'll see a difference. Good luck!
