The range of ADHD is wild, I'm just always hungry, I have to consciously stop myself from randomly eating any food in my proximity. If there's a box of crackers, or leftovers in the fridge, I'll eat them, even if I ate an hour ago, if I don't make a conscious effort to remind myself that I ate a meal already. Adderall has helped with me being aware of when I'm not actually hungry, but when the drugs wear off in the evening, I have to be careful about cruising the kitchen/pantry.
