In reply to link: Another thing to remember, is that in the UK its 80mg per 100ml in the UK, on the continent its only 50mg, so the idea that a couple of pints is ok doesn't work in Europe. Particularly as most beers are at least 5% by volume.
If you're fortunate to be young enough to have to ask and taking into account the price of bevvy in Switzerland your pocket money will probably only extend to a 25cl glass of bier on your last night out anyway.
