This thread poses a challenge for me, for I am an American of Scottish descent and have been a heavy yet healthy drinker for a long time now. Until after college, I was under the impression that nothing should be memorable after drinking, a blackout was one's reward for a job well done.
I'm now a functional alkie who drinks with his pinkie finger raised, I drink for the enjoyment of whatever spirit I have at the time. So, L'Chaim!

Q's of Miller High Life whilst playing basketball til the wee hours on humid Iowa summer nights. 2 quarts would get it done, 3 and the jumper wouldn't fall anymore.

The first Fat Tire I ever had, at Ed's house in Colorado.

First time I ever put away a bottle of red, Penfold's Shiraz/Cab. Erin was working behind the bar. One day, I will fuck her.
