I eat all.night.long. Everytime I get up to pee, I eat something. A small pack of fruit snacks, small bowl of jello, pudding cup, tea biscuits, something. I literally can't go back to sleep unless I get up, pee and snack on something. About 4 or 5 times a night. And it is all junk food. All of it.
I'm only up 30-something pounds too, by some miracle. But yeah, I stuff myself before i go to sleep and then eat all night.
