I'm sure absolutely no one is surprised that I have had copious experience with Absinthe. A girl I used to see brewed the stuff, actually.
Most stuff you're going to drink isn't gonna be what "real" absinthe is. One time, tho, she got a hold of some actual essence of wormwood. The drunk/high that I had that night was fucking amazing... everything was SOFT. There's no other way to really put it, and it was just right, too.
Absinthe does give you the worst hangovers known to man, tho. No trick you think you know will save you. Drinking water, gatorade, whatever. Try it all, no matter what you're going to wake up a couple hours after you pass out and think your brain is trying to crawl out of your ear. It's all part of the charm of the drink, really.
