No money 3 days a week!

This year I have a new plan that I want to try and live by...

 I will go 3 days a week without spending a penny... I really need to be come more accountable for my spending and really just learn to save at all cost. 3 days a week of no wawa no anything.... I CAN do this because really I need to...  I know i'm not  the only person to have a spending issue... but I can't tell someone else how to do it. 
 The days that I do spend money will be documented... Do I need every single item that I bought?   If not it will be cut out of future spending habits! 

I can do this!
