Not spending but not saving either

The other day I was reading a post about having a few days a month where you don't spend any money at all.  Well I've had a few of them now and I'm feeling a bit down about it all.  I really like to track how much money I am saving when I'm out.  If I use a coupon I write the savings down. When I use my club card at the store they tell you how much you saved.  I track my savings and it's nice to see that number grow every day.

I know I'm not spending anything today but I hate that I can't save money at the same time.
