I remember I was eating very healthfully for a while and then when heading to my job I absolutely needed food quickly and went to McDonalds. I felt pretty crappy a few hours later. The lesson ironically was that I should be eating more mcdonalds because that's the environment I live in and I should be better acclimatized :-)
