let me tell u all a story that happened to me last year
i had not had mcdonalds for years cuz i ddint want my face to break out
well one night i had a bigmac and fries and within half an hour my face had broken out in big itchy red welt pimples
it was horrible
plus i craved it for weeks after i swear they put stuff in it to make u crave it
I used to abstain because I thought it was utter trash as well. It's bad, but in a pinch it's better to eat something rather than nothing. My diet is otherwise clean enough so since a couple years ago I've had McDicks about a dozen times. I never break out after eating it anymore, but I do crave it severely for weeks on end.
I'm craving that shit right now... I love gourmet food and exotic meals too, but sometimes it's nice to have a greasy ass burger and salt encrusted french fries. It mixes things up.
