Yesterday I had a really strange reaction to dark chocolate. I ate some sugar-free 100% cocoa dark chocolate, and for the following seven hours, all sorts of things started happening:
• Almost immediately afterwards and for some six hours following, I felt really giddy and hyper-energetic, like I expect one would feel after ingesting too much caffeine (I never drink coffee or any highly caffeinated beverage, so I don't know, but that's my guess).
• After a few hours, I started to feel nauseous. This lasted for two or three hours, with varying intensity.
• When I was at the bathroom, I had this sudden bowel movement, and my heart rate suddenly jumped for a few minutes before settling down gradually.
• I also felt like I had a fever of some kind, though that passed within an hour or so.
I feel completely normal now, but I had to call 911 and talk to a toxicologist at a point, because I thought I was going to have some serious problems.
Does anyone know what might have been the cause of this? I've never had a reaction like this to anything else in my life.
