^ wine has the same effect on me. It's almost an instant headache.
(Gotta love the Guinness though!)
The best hard liqour I've ever had, which did not give me any hangover at all, is Un Emile 68 - an absinthe distilled in France.
Even though it is 136 proof, it has a lot of herbal qualities that, while getting you very drunk very fast, it is a different kind of "drunk".
It is a very clear-headed, awake kind of intoxication. You feel the effects of the alcohol quite strongly, yet you don't get groggy, tired, dizzy, or any of that.
If it wasn't about $120 total (Un Emile plus shipping), I'd have a bottle in stock at all times.
All quality absinthes have this kind of clear-headed intoxication. The Jades are an excellent choice, but a little more expensive.
If you like to experience new drinks and things, I highly recommend giving absinthe a try! (But stay away from Sebor, King of Spirits, and Le Fee - that's mass-marketted fake stuff)
If it's not Un Emile, a Jade (Nouvelle Orleans, Eduard), or Francois Guy, it's probably not worth buying. Check out
