You stayed in last night. You skipped the work drinks and just ordered in pizza instead. You were very well-behaved, didn’t do any shots, and didn’t end the night by throwing up on your shoes.
So why are you being punished with a pounding headache and intense nausea this morning? Why are you hungover when you haven’t had anything to drink?
It’s all down to the copious amounts of junk food you ate the evening before.
See, the food hangover is a real thing. Really. It’s not just something you made up the last time you felt rubbish.
