So there's good news and bad news. The bad news is that you can't really avoid a hangover if you choose to drink. The good news, however, is that you can have a less-bad hangover by selecting the right kind of booze.
DNews explains why certain alcohol makes you feel shittier than others. Since it's a little science-y, we'll just cut to the chase: the darker the liquor, the worse the hangover. So, choose clears (e.g., vodka) over browns (e.g., whiskey), people. Puking in the stall at work just isn't a good look for you anymore.
