> or Paracetamol as we call it here in the UK

Mildly amusing anecdote: years ago I visited my then-company's office in London (I'm from the US), and fell sick during my time there. One of my London-local colleagues recommended I get "Night Nurse", and told me of the magical virtues of paracetamol. I'd never heard of it (either the brand name or the drug name), and assumed it was some great drug that for some silly reason the US FDA decided not to approve. It worked perfectly well, but frankly no better than what I'd take at home.

Much later I looked up "paracetamol" and discovered it's the same thing as acetaminophen... "oh, Night Nurse is just the UK version of NyQuil", I realized, somewhat disappointed, the magic lost.

> I'm always surprised at the hostility to Acetaminophen

I wouldn't say I'm hostile toward it, but the number one cause of headaches for me is alcohol consumption, and I was taught that alcohol plus acetaminophen is a strict no-no. Ibuprofen -- in the recommended dose -- is generally fine with alcohol. (I don't binge drink anymore, but as I get older, even 3 or 4 cocktails over the span of 4-6 hours can give me a headache later.)

But when I come down with a cold, it's (the cheaper, generic version of) NyQuil for me. A bonus is that NyQuil also contains dextromethorphan (cough suppressant) and doxylamine succinate (antihistamine) (or phenylephrine in the non-drowsy DayQuil variant), which IIRC Night Nurse/Day Nurse did not include. (Looks like it does contain dextromethorphan and promethazine now; not sure if it didn't back then, or if I'm just misremembering.)
