Ummm, Cheeseburgers! Doubt that it was the preservatives. But, there is a ton on calories (and salt) in one. Decent amount of protein too. I am guessing that the extra calories were the problem. You needed to burn them off and no way to do so?
It was a cheeseburger meal. Whatever is in there must be pretty damn strong because I didnt settle down for like 24 hours. Unless Im just extremely sensitive to it. But the next night I felt so much better.
Interesting! Do you remember what you had there?
