I had NO CLUE about potential for liver damage due to too mych tylenol until I came to this site. I FREAKED the first time I read about since I had only ever taken vicodin ES which has 7.5/750 mg. in one tablet. I have switched to Norco 10/325 - half the tylenol, because I wanted to cut down. Sometimes, it doesn't feel as effective. But that's okay since I don't want to kill my liver.

I had some tests done before my surgery about 5 months ago and everything came back fine - including liver. I don't think taking a lot in one day is a big deal. It's the long-term that can do damage. And be sure not to mix alcohol and tylenol on a regular basis.

But can anyone tell me, if you did have liver damage from long-term tylenol use, besides tests, how would you know? Would you feel it? Do you just drop dead?
