We have already, all but, quit eating out. Between me being low-carb and the boys trying to stay away from gluten, eating out isn't really that easy.
So this month I am going to kick the soda habit. Since DH still drinks it, I will still have the temptation in the house. But, for me, soda is a convenience thing when I don't want to drink water. So next time I am at the store I am going to pick up some glass bottles and start brewing tea. I figure if I fill several days worth of bottles at a time then I will have no excuse to grab the soda.
That should shave about 20 or 25 dollars off my grocery bill each month, maybe more!
