I love coffee. In fact, I'm obsessed with the stuff. But unfortunately, I'm allergic to it too.
I used to drink a lot of coffee up until a few years ago when I developed a sensitivity to it, due to my over-consumption. Now, the minute any caffeine (from coffee beans) enters my system, I get muscle cramps and severe palpitations. Not pretty. I'm allowed to have decaf, but it just doesn't taste the same, and I still get the same symptoms, even though they're much milder.
