I've never heard of someone dying from tequila shots here!

Although I do recall attempting to sink a bottle of whiskey through a home made funnel (dentist chair style ) at a house party when I was about 16/17. Luckily threw up a lot of it immediately but still went mental and passed out in the bath in my own sick for about 10 hours. What's the worst state you got in your younger days??
