Well, if you eat three meals a day, that's thirty days, or a whole month, with eating nothing but semen.
No matter what they say, I don't believe it. Especially if her 'cum diet' doesn't allow her to drink any water.
I was very, very sick a while back, and couldn't really do much aside from drinking water, and eating those protein shakes. I lost over 30 pounds in weight, and felt pretty sick/weak.
So, while I'm sure it's a great publicity stunt, I just can't believe it to be physically (and absolutely not healthy) in order...
