this is fascinating stuff! no need to worry about liver damage with ibuprofen and alcohol at any reasonably combined level(bleeding from a stomach ulcer would be a bigger worry, especially if over-indulging). tylenol and alcohol would be the real concern. i have also gotten 2 of my worst migraines at rangers games(both several years ago) and one at a saints game(i rarely get migraines and all three happened within 1 hr- also all three involved budweiser). so that gets me to wondering(mostly about trace wood residuals as a migraine trigger). also the contaminated line thing is somethinhg that i've never thought about. there is some research to be done but dont look at me - i'm only an m.d.
