Let the betting begin!

My roommate's Mom found out I love peanut butter. So, out of the kindness of her heart she decided to buy my possibly the biggest jar of crunchy Jif peanut butter that I've ever seen. The thing she doesn't know is that while I love peanut butter I have almost no self control when it comes to the stuff. As much as I would love to eat that peanut butter she gave me I know it would be gone before the week was out, and my face and hips would seriously regret it. So, I have decided to try and go the entire semester without opening the jar. If I last that long I plan to reward myself with some sort of peanut butter fantasy creation that has yet to be determined. If I last that long. To give you an idea of how hard this might be for me I'll admit to that fact that as a kid my mother had to hide the peanut butter from me. My roommate bet me 5 dollars that I won't be able to do it. I think I can. It's going to be torture but I'll tough it out. ;) So the question is, what do you think?
