The short answer is yes, you can play golf hungover. However, it's definitely not going to be an overly enjoyable experience. Golf is a game that requires focus and concentration, and when you're dealing with a pounding headache and queasy stomach, it's going to be tough, to say the least. There's something about being out on the course, fresh air in your face, and hitting some balls that just makes a hangover seem almost manageable. Of course, you probably won't be playing your best golf if you're hungover, but hey it's still golf!
