If you see anyone passed out from drinking, put them on their side and call an ambulance. Don’t assume they’re just sleeping, they may have alcohol poisoning and it can be fatal.
This just seemed like a relevant thing to post today I guess.
ETA: on average, the body takes an hour to process one unit of alcohol so take that into account the next day. Drink water to alleviate a hangover. Eat a full meal before you start drinking. Have money for getting home in a separate place from money for buying drinks (e.g. sock). Fully charge your phone before you head out. Remember “weed before beer, you’re in the clear. Beer then grass, you’re on your ass.” Don’t drink and drive.
