drunk eating

i couldn't think of a more creative title...
i have a big problem. i have been so good eating, well, at least better than i have been in the past. i have gotten SO much better at eating out at restaurants and not finishing everything. last night i went to this burger place and got a hamburger for dinner..and i only ate half of my burger and fries and let my date eat the rest. BUT now my big problem has been eating when i am not hungry when i get back from the bars at two or three in the morning. a lot of times my roomate is asleep or not here, so i'll just raid the kitchen. this didnt used to be as big of a problem because i didnt go out that much...now that i am not dating anyone, i have been going out a lot more and this has really become a problem. i dont know what to do about it...all i know is that last night i had a piece of pizza, two cupcakes, and two cookies between two and three am. ya, definitely not healthy :/
