4. You have too much alcohol in your system
If you’ve been drinking all night and you’ve woke up sweating, it’s because of the alcohol. When your body sweats during a hangover, you are literally sweating out alcohol as your body is trying to get rid of it.
You will notice the smell of alcohol from your sweat, but your breath will smell of it, too. Amazingly, it doesn’t matter what alcoholic drinks you drink, either – all alcohol is the same, and when the body breaks it down, it creates the exact same smell.
