Hard, especially in some cities. It basically means not going out or not drinking, in many places where you have to drive to get anywhere, like Southern California. Young people always want to go out, and usually want to drink, so leaving the car behind doesn't work. Designated drivers probably have a better chance of working, or not drinking as much or stopping drinking a couple of hours before the party is over, as well as drinking a lot more water to dilute the booze and help piss some of it out.

Practically speaking, moderation is better than nothing. As is learning to have a good time without getting totally cranked.

Definitely the "But I'm still a good driver" baloney is a total dead end. Denial or thinking you're special is no help at all.
