Haha! I remember myself every time I go to the groceries. I always end up buying more than what I had planned on buying. Now that I have read this, I might want to eat first before going to the grocery.
I realized this a while back that's why I try to eat something before going to buy food cause if I didn't i'd buy everything I saw cause I was hungry.
I always try to plan my shopping trips so usually I am not shopping out of desperation and hunger (and I stock my shelves and freezer as much as I can). I do believe there is truth that when you are hungry you buy more and things off "the list". I would rather fix a small snack and then shop or find something to cook or eat at home and save the shopping for the next trip. Planning is everything!
