Most people won't think twice about calling in sick to work because of a hangover, but you'll let your boss know that you're not coming in today because you don't feel well - aka, you need more sleep. You are just too tired to adult because getting dressed, going to work and actually working for a living is exhausting. So if you've ran out of holiday time and your weekends are busy with napping and eating, take some time off to rejuvenate your body and your mind. Just be sure to not put on Netflix because even if you put it on as background noise, you're going to become far too invested in whatever you're watching.
