I feel bad if I waste food, but thank the gods that we have carryout boxes, tupperware, and refrigeration. I love leftovers, especially when it's late into the night.
Ever since I tried to starve myself to death it's been harder to eat as much as I used to, but I still digest my food quickly. I've become a chronic snacker to not get sick, either through bloating or over-hunger like a damn seesaw.
