I'd begun Advair right before the burn, four days only, and dropped it because the mouth rinsing thing and remembering to use it was too much for me. I did fine, no coughing, wheezing or chest pain on the playa or now. Haven't used my inhaler in over two weeks. I only used scarves during the whiteouts too. My asthma settled down wonderfully on the playa.
Know what gives me flu symptoms? Fatigue, body aches, sore throat, swollen glands, cough, headache? Any product with sodium/potassium benzoate in it. Flavored waters and diet sodas have a lot of it. Worth checking if you think you may be sensitive, just start reading labels. I feel and look at lot better since I weeded that crap outta my system. I know, I nag, but if it helps one person it is worth it.
These are not my fuckos.
