Now that would be fascinating. Britain has a deeply entrenched drinking culture. Regularly getting drunk to the point of vomiting and passing is very common. The managers where I work all live away and stay in hotels when they visit my town every other week. They all go out and get wasted on a Wednesday night (with company funds, totally legitimately) and often don't come into work Thursday so they can drive home in the afternoon when they sober up. All totally normal.
Ban advertising, pub drinking and cheap supermarket booze. Inflate the price and run a massive anti-drinking campaign. It'd be interesting to see how long it'd take for the tide to turn. Also, if we end up going the way of America during prohibition with illicit alcohol flooding the streets, how long that would take to die down and for people to accept it.
But it'll never happen. No politician is even going to think about limiting the availability of alcohol in this country. They'd be so unpopular it'd be political suicide for them and their party.
