Interesting Article HERE, but I have to disagree.
The worst hangover I ever had was a Vodka one. Now granted, it was cheap cheap CHEAP well Vodka, but it was Vodka none the less.
Also, I wonder where they get the funding for these studies. I could have told you that its the particulates that cause headaches.....and I dont have a PhD.
Of course, no body asked me to participate in the study....man, getting paid $450 to get drunk sounds pretty close to being the greatest job EVER.
Oh well, maybe next time.
