This guy is drinking noting but Pepsi Holiday Spice for 45 days (similar to the movie Super-Size Me, in which a man ate nothing but McDonald's food with frightening effects). He's keeping a blog to document the impact it is having on his body. Snip: "I instantly started sneezing, which made me $@#$@#$@#$@# my pants and on top of the horror I got another bloody nose. Luckily no one was home when this happened."
