I certainly learned over time what my triggers are. As I've gotten older, anything bad for my body ultimately makes me sick in some way. I have it bad enough now that I'm gonna get it for any reason, it's even become a problem that occurs when I haven't eaten after a while (12+ hr).

Luckily I don't like sweet tea or other full sugar drinks (you can pry diet coke from my dead hands). Hadn't heard about the ice thing though.

My biggest triggers are fatty foods, tomato, chocolate, and palm oil.
