Ah, then forgiving me for thinking that you might be one of those (many) people who believe that tequila contains some other kind of psychoactive ingredient other than alcohol.
Anyway, I couldn't agree more, particularly with respect to blancos. Beer and whiskey tend to make me feel both physically and mentally sluggish, whereas tequila makes me feel more energetic and more clear-headed (up to a point, of course). The more the tequila is aged, the more it affects me like beer or whiskey. And I've got a friend who claims that blanco makes him a happy drunk, whereas reposado or anejo makes him an angry drunk. (If anybody knows why, please chime in!)
I've heard people put the different effects and after-effects down to the amount of content of tannin in the particular drink. I don't know if that is the case but I think there may be something to it. The lager I drink is brewed in slate rather than wood, I've found that more refined too. But again, certain drinks have their very own character, gin has been long noted as a depressant, which in my experiences of playing many bars, has been confirmed with a not too shabby sample rate. Every female I have witnessed full to the brim with gin, has been reduced to tears and sobs by the end of the night. And it was nothing to do with me, those times.
