Anyone who drinks or takes tylenol regularly, or both, should be taking NAC. It is an otc supplement, and is what is given for tylenol overdoses. I had a patient in the hospital once who had taken tylenol to attempt suicide. She was given liquid NAC. The liquid is nasty; smells like permanent wave lotion. The otc stuff is a capsule that protects the liver. It smells a little funky, but not like the liquid.
Good info, thanks for passing this on.
