Set a limit for yourself before you start. Same thing as gambling, really.
Get some water and food to consume along with it.
Drink in a reasonably safe place. Preferably with friends around.
Stuff tastes somewhere between corrosive and like something good. Like soda but without the excessive sugar and the carbonation. Humans like putting slightly painful things in our mouths.
The mental effects seem useful at low levels, then sharply falls off in usefulness until you're unconscious.
At some point alcohol was pretty important to starting this big weird civilization thing. It's probably the simplest recreational drug to make, which would explain why it's so important in our culture.
I won't judge anyone who won't touch it, wither because it tastes bad or because it messes with your brain. I might end up judging people who drink so much they totally lose control, sing loudly, puke, fall asleep, and wake up with a horrible headache and start complaining about it as if there were nothing they could do to prevent this. Sorry.
It's not legal to drink under the age of 21 where I am, and I'm 20, so I don't. I've had sips of other people's drinks to get an idea of the taste, but never had a whole cup. This means I obviously don't have much personal experience here. I'm kinda interested to find out what effect alcohol has on me, but I really don't fancy the idea of having more than a cup or two.
