I'm a bit of an insomiac, although I make up for it later in the afternoon.
But I've noticed, usually around 1am, 2am and even now at 3am, I feel like some fast food, like KFC or McDonalds(also known affectionately in Australia as Maccas).
The fast food joints aren't open this late at night (except for Maccas on the weekends) so it's not like I can go out and get some (or fast food for that matter). I do have some food that I munch on, although I'm not going to go to the trouble of making a chicken burger at 2am!!
So I just tell myself that I can get some Maccas or KFC tomorrow for lunch in an effort to quell my appetite. Then, the next day, I don't feel like having it for lunch, until later that night when I get the same cravings again (and no, I'm definitely not pregnant, lol).
Grrrr......
