All this stuff - tylenol and advil - is very dangerous in certain conditions that are not widely known.
Our friend drank moderately but took Tylenol regularly. The coroner said her liver was worse than someone that drank a qt of hard liquor a day.
Another friend - just last week - developed a flu like condition and did not eat for 3 days but took several advil, nyquil, etc. HIS KIDNEYS SHUT DOWN and the Dr said it was the OTC drugs on an empty stomach.
That is horrible. Best of luck to him. However, I will stick to my policy of mixing Darvocet and beer at night, on an empty stomach. I had a mishap on my mtn bike and abraded off a good chunk of skin, and it's the only thing that lets me get a good night's sleep. (because in addition to the throbbing pain, my wound sticks to the sheets and wakes me up.)
