Spend Nothing for 10 Days

I wonder if I could truly do this...

I am terrible with money. I'll admit it. I never admit it...I pay my bills on time, I have a (modest) savings account and I eat cheaply for the most part (Cheerios anyone?) I have spending vices like clothes, shoes & coffee and all of that adds up QUICKLY. My thinking lately has been "garage sale! garage sale!" just to offset some of the money I've spent and get rid of the crap I've accumulated. Not spending a dime for 10 days terrifies me. What if something awesomely cool comes up? What if I really need new black pants? Then the rational side pops up and says - dude. It's 10 days. Come on.

I think I should try. Granted, this may go the way of my trying not to eat meat for 10 days...
