Why are you yelling at me? I was answering the question wenron8062 asked saying what they were told about TylenolPM. The they was whomever told them that. They wanted to know why someone would say that, I just told her. We were talking about dementia not liver disease from high dosages. If you want to know where it came from feel free to google it. I read it ages ago. NIH, Harvard Health, Scientific American, etc… I’m sure you can find it there.
