About 20 minutes after we finished I threw up, and I initially thought it just didn't agree with me or something, but then the next thing I knew I had hives everywhere, my mouth and throat were itching, and one of my eyes was starting to swell up.
I epi-ed - the swelling started going down almost right away - and my sister drove us to the ER, which is just a few blocks away from where we live. At the ER I got to experience a biphasic reaction for the first time (woohoo).
