I've already changed my alcohol consumption. Firstly, I cut down on my overall consumption: most days I don't drink any alcohol at all, and at events I try to stick with 4-5 beers maximum. I sometimes stretch that a bit at festivals, but those only happen once every ~3 months or so and the intake is usually spread out over 8-10 hours.

Secondly, I very much prefer less processed types, such as wine, whisky and unfiltered beer. I stay far far away from alcopops and similar drinks.

It may be anecdotal evidenece, but I get far fewer hangovers now, even if I drink to the same amount as I used to.
