Ever have one of those days where you just can not wake up? I typically have them only on days ending in "y" myself, but I hear some people have them all the time. In my case it could be that I drink about 180 ounces of Dr. Pepper a day, or maybe that I stay up until 3 a.m. nearly every night watching "Family Guy"... or maybe I stay up until 3 a.m. because I drink about 180 ounces of Dr. Pepper a day?

Anyway, if you are like me the effects of caffeine do not seem to affect you the same as the do other people, thankfully, Jenna Marbles has done a little "research" like only she can, so the rest of us can see how caffeine affects a "normal" person.

Thanks Jenna!
