Aver, I have suffered some of the same I'm thinking you have: stims can give me more anxiety, mess with my sleep and make me crash, all which leads to (possibly a small) increase in average calorie intake. If that increase is even 5% it could totally offset any effect from the stimulant. To note is that all of these essentially work by messing with your energy balance (I.e. your caloric expenditure). Lipomorph on the other hand is a completely different approach.
