midnight McDonalds

After reading "fast food Nation" i stopped eatting Mcdonalds and most fast food for about two years and then feel back on old habits. Lately I have been trying to eat most of my dinners at home. I need to eat most meals at home or at least meals that i have cooked myself. but....
Friday, I went home and was exhausted, fell asleep and when i woke up it was a almost 11pm. I was hungry and there was no food that did not involve cooking, so mcdonalds it was. I feel some kind of way about eating there but... what is done is done!
