Yea.. I used to like OD myself almost on adderall and shit, it made me sweat like a dog, and also didn't make me want to eat.. period.

Even now, I don't eat. Ever. And I mean it, seriously.

The only meal I eat all day is 1 at ~7pm. After that, I only eat some chips or something if I get munchies from smoking. I eat no breakfast, no lunch, and nothing in between, and have no idea why that would affect me badly. Any time I even try to eat breakfast/lunch, my body doesn't even know wtf to do with it, and I feel bloated and shit all day because my body isn't used to it.
