Movie theatre popcorn with the fake butter stuff. How I love it, how it hates me, which is why only go to the movies a couple times a year and have some, cause it's totally worth the pain. Dairy products totally wreck me, so no pizza, no ice cream, no milk, no cheese, no nothing tasty and dairy. I loved milk when I was younger, wish I could still drink it. Sigh. And deep fried foods, if I have an excess of them (that would be like 2 orders of fries in a 2 day period) make my system revolt, shut down and refuse to move forward. In fact, the fatty foods will sit in my stomach, bubble and churn for a couple of days, produce the most nasty farty smelling (and tasting, yuck!) burps and finally cause me to barf. Very, very unpleasant. So I avoid the fatty fried foods like the plague!
