"Before 3 am"? None of my business of course but do you really eat in the middle of the night? Like then you stay up? I know i sometimes have problems with my wake/sleep cycle too, but you even beat me. I know mine is due to my mother working afternoons when i was a baby (from 6pm to 2 am), i used to stay awake in bed waiting for her to get home. Then while i was working, i often got called in the middle of the night, and at one point worked the nighttime 12 hr shift for almost a year. I was pretty much a basket case after that.
