Those little habits deplete wallets, don't they? I also love bags of chips. For a while I tried planting potatoes in the back yard. My granddaughter loved helping me dig them up, washing and peeling them, and cooking our own potato chips. But it's a battle keeping wild animals from messing up the plantings, and so much easier to buy the chips. Popcorn is an alternative, and much cheaper if you pop your own.
Plus you gain weight. I feel like a trapped gerbil in my cubicle. I notice when I have time off from work I lose weight.
