Always eat when you drink
While the Harvard research suggests it's wise to factor in those cocktail calories, it's actually more important to eat right than to eat less, the experts stress. Skimping on food in order to "make room" for drinks will only backfire and send you straight to the bottom of the candied nut bowl. Here's why: Most cocktails are loaded with simple carbohydrates, "so during a night of drinking, people end up with soaring blood sugar, followed by a 'crash' that leaves them ravenous," says Jason Burke, MD, an anesthesiologist and hangover researcher who runs a hangover treatment clinic in (where else?) Las Vegas.
