Yeah, stimulants kill appetite pretty hard, I'm not surprised. Adderall and Ephedrine are the classic weight loss solutions for a reason, also makes you sweat more.

Just make sure you drink tons of extra water to make up for it. A person with a normal diet and no medication can get away with not drinking anything, they're getting their essential hydration from food. You're putting out way more water from sweating, and you're not getting as much water from food.

And if you really want something to cancel out some stimulant side effects like appetite, taking magnesium can make quite a big difference.
