I don't have a good time/don't get as much as I could out of some conferences because of this issue. Due to a medical condition I have a sensitivity to chemicals. Just smelling alcohol (or cigarette smoke, detergents, cleaning products, ...) makes me ill. It's not something that I--as some of the commenters here have advised--can learn to accept.
