>I can't stand sugar and honey, though.

Well that's cool, looks like we have pretty much the same opinions on this but quite different tastes.

>This might be a DQN, but what is quinine? I'm too lazy to look it up.

I don't know about DQN, but I'm happy to get an opportunity to ra...explain this!
Standard wikilink: http://en.wikipedia.org/wiki/Quinine
"Quinine, C20H24N2O2, is a natural white crystalline alkaloid having antipyretic, anti-malarial and analgesic properties and a bitter taste. It is a stereoisomer of quinidine.". It is the classic anti-malaria drug, traditionally extracted from tree bark, and still used against resitent malaria.

Supposedly gin and tonic comes from Brits mixing gin into their anti-malaria drugs to make them taste better: tonic water very much gets its taste from quinine. Other than tonic water, it also gives taste to at least Schweppes Bitter Lemon (/similar drinks). The drug solution is/was much stronger than the soft drinks, and must really be quite horrible-tasting.

Finally, as a bonus quinine seems to be fluorescent: transparent tonic water should therefore glow under a black light. I am yet to try this though. I just love quinine to death.
