Allergies - Bees, wasps, hornets, etc. If I dont get the bee needle in time, then i can possibly die most horribly. I've been stung lots of times (they like to sting me, and will search me out in a group to bite), and the reactions are getting worse and worse. I was rock climbing and one bit me on the arm, just above the elbow - i tied it off with a piece of rope to get to the hospital, and my entire arm looked like someone took a rubber glove and blew it up all the way to my fingertips.

Sensitivities - Wheat, gluten, yeast (so, anything thats a bread) makes me feel unwell for days afterwards; shellfish like lobster, crab and oyseters will make me throw up about 2 hours afterwards (and its really disgusting, but it will come up the same way it went down, completely undigested -- i guess my body can't process it. i may as well be eating rocks), but thankfully no other reaction than that.

Wierd Other - Aspartame and artificial sweeteners. Instant migrane, i've had 1/2 my body go numb a couple of times after drinking a can of diet soda. So, I avoid those, since I like to be able to see straight, and not feel like theres gnomes in my head with pickaxes.
