Alcohol is empty calories, but it can lead to good times. You’ve behaved all year, you can have one night of fun. Make sure before you do that you check the supplements you’re on and how they behave with booze. If you’ve been taking L-tryptophan to help you sleep, you could be in trouble after a few drinks. Check with your doctor, and don’t do anything that could lead to damage.

A glass of champagne runs around 200 calories, so it’s not going to be a huge indulgence to have a drink or two. The

riskier part is the food that you ingest while drunk (or as a hangover breakfast), so take in a glass of water with every drink. Enjoy yourself, and get ready to pay for your sins in the gym next year.
