no i just dont drink often.
people who rarely drink can have far more booze then some alcoholic before hes drunk.
The forget are you talking about.
If you drink, and never drunk anything alcoholic before, you get drunk much faster because your body instantly processes(?) the alcohol. But if you drink beer every day(one - two per day), like lets say me, your body gets used to it and you'd need much more alcohol to get drunk.
So, instead of one Vodka it takes two now to make me fully drunk. It takes 8 Beer on a full stomach and 5 on a empty one. Sometimes I don't even get drunk at all.
