My character is a wealthy, upper-class Ivy-League college boy in 1963. It's the morning after a party and he had too much to drink and has woken up with a killer hangover. His friend offers him _______ to kill his hangover. What would he have been offered in that time period? At the moment I have aspirin as a placeholder but I get the feeling aspirin as a hangover cure is a more modern thing. Googling it did not help.
Thanks in advance :)

Time: 1759
Place: Paris
With what kind of gesture and level of physical intimacy would a young artisan (clockmaker, inventor) say his final goodbyes to a male mentor/friend with whom he has worked closely for months? (hug, kiss on the cheek, bow, or just wait for a fatherly pat on the shoulder?)
The young man (25) isn't a noble, but he's reported to have been introduced to the British court not a year later (showing off his inventions and musical skills) and then went on to make friends with a couple of British writers and musicians, so I figure he probably has relatively good manners. He's also a bit reckless and impulse-driven, though.
The older mentor (40-ish) isn't from this culture, has zero problem with PDAs in general and no homophobic hangups. He will literally go with anything the other initiates. Or he'd most likely bear-hug him if that's okay in this culture.
I honestly don't know how to google this. I'm hoping people who are familiar with the period from books and movies can give me some pointers on what would be appropriate.
