I did that as an experiment for like 6 months...not $2 but I set my food budget just for my own food at $100 a week. 2 big ass packs of chicken breasts, 2 big ass packs of chicken thighs, big sac of rice, bunch of brocolli and okra, like 10 gallons of water and like a dozen bananas. Ate like that pretty much the whole time, never went over $100 a week, was always around $80-90. The amount of money I saved was mind altering. Budgeting can/will change your life, believe me...even if you're up up, budget anyway so you can stay up up
