Never touch vodka, gin, tequila, etc ever again. I switched to beer because I got tired of spending parties known as 'the guy sleeping outside'.
Probably the worse occurrence was when I was 16, and my parents had Polish Spiritus around the house - (192 proof)
The last time I saw my Dad use it he was cleaning silverware with it.
So naturally we thought it would go great with Pepsi.
My parents were away so I had some friends over.
I remember the police showing up at one point, then I blacked out.
I woke up the next morning with vomit literally everywhere. Don't recall a single minute of it. My sisters said I was throwing up in my sleep. like so many deceased rock musicians (Bon Scott, etc).
That was pretty much it for me.
