That takes me back a few years... when i learned a valuable lesson... if I want to get laid don't touch the vodka... Everyone has their weaknesses and vokda is it for me.
I went to a party where an that an old special friend invited me to... I did the dreaded beer before liquor crap... and the next morning i woke up soaking wet... inside a bathtub... I had to call my friend to pick me up in the morning because he took my car home... yeah I know..
My special friend called me a couple of days later and told me that we got into it hot and heavy in one of the bedrooms and got to the point where we were going to take care of business and I had to stop suddenly to puke my guts out.. Well it was pretty much over after that. I dont remember a damn thing from the point were i took a few shots of vodka...
So to answer your question.... lite buzz is just about right... anymore and youll wake up in a bathtub soaking wet in all of your clothes...
