Excellent report and always great to read them. My favourite bits are the sarky comments and pics!
I don't understand why people in the US use "Tylenol" for sleep. It's a pain medicine, not a hypnotic. And not a good pain medicine. So the company has been fooling people for years with their "Tylenol PM" which has a sleep "aid" in it. But you don't need the Tylenol bit. And your liver certainly doesn't. So why not just take a sleep aid or diphenhydramine instead of this stuff you don't need?
