The standard beer here in Germany is 0.5l at ~5% alcohol content, which comes down to 2 1/2 standard drinks. And it isn't unusual to drink 2-3 of those. The problem arises when this goes from an occasion (meeting with friends) to become a regular thing. The body and mind also becomes much more resilient to alcohol as you drink regularly. During my early 20s when we went out to bars a lot, it was normal to drink 4 large beers and feel tipsy, not drunk.
