Alcohol vs. Caffiene..... hrm.
I drink more caffiene day to day, what with the morning cup of tea (no, not a cuppa, not a cuppa, I'm not a frickin Brit!) -- in fact, haven't been drunk since, er, returning from the Land of Much Beer And Other Alcohol, 'bout four months ago -- but I don't really need either, so it still comes to a question of pleasure/enjoyment.
I'll take my tea, it tastes better.
Besides, I can be pretty "drunk"/slaphappy with no alcohol whatsoever, so....
