I feel your pain about going to the store intentionally to binge and then purge. i moved out of my parents house to avoid having junk in the house, and being in more control of what i was eating. When i needed to binge, i figured i wouldnt make the effort to drive to the store and spend the money. Wrong. I bought everything and anything i thought looked good, and was halfway through it all before i even got back home. Its so hard to try to control. even when my trigger foods arent in the house.
