See, before I got my carbs and thus my insulin under control, and before hubby started eating healthier as well, we used to stop at least 3-5 times a week to get treats ... chips, cookies, banana bread, chocolate bars, etc. He had a special weakness for raisin toast, which seems to be half price fairly often. Oh, and hubby had to have ice cream for dessert every night as well. He's given that up for fruit and yogurt these days, and avoids the other temptations at the store now. I don't stop after work anymore unless it's for a bag of salad or something like that. I reckon we easily spent another $40 each week because once you're in the store you seldom get just the one thing you came in for. So if anything, we may be spending less now.
I don't miss those treat runs either, I don't even think about them anymore. When insulin was controlling me I was on autopilot some days. I knew I shouldn't and that I'd feel bad for doing it, but I also felt powerless to resist, the cravings were that strong. But I don't have cravings anymore. I honestly don't think about junk food anymore. That truly is a powerful, wonderful feeling. I remember reading someone thought they would never be able to stick to this if they had to battle their constant desires to have forbidden foods ... they were surprised to find that's just not an issue, cuz those desires or cravings simply go away. So honestly I've found it very easy to stay on track.
