Thats another good way to do it, personally I think that is a lil extreme, but none the less a good habit and some people.cant even handle 1 drink(like my wife who is.drunk on 1 drink) some people can drink 6+ beers and not feel the effects 1 bit, but thats still waay over the legal limit wether.they feel it or not and enough to catch a serious charge.if.they do.wreck, even if its not their.fault.
