Wow, girl, you are doing SO WELL!
Sorry I haven't stopped by earlier... I actually read your post about coming up with substitute things to do to distract you or to replace your bad habits, and then I wandered around town all day thinking about it, and thinking about things I could say. I had come up with some really good ideas, but then I stopped and realised what a total hypocrite I would be to write them down. You see, all these problems you have, I have them too. Not exactly the same ones, but the same kind of concept. I was going to try to give you some possible solutions, but then I realise that I'm not even trying to look for solutions to these problems in MY life! I just accept that this is what I do and don't try to change it. In fact, I like it. So you are fifty steps ahead of me.
One thing that I WAS going to ask, though, is to try to figure out one major thing: When you bundle the kids in the car and run off to get that iced coffee mint bonanza, what is it that you are actally craving? Is it that process of bundling the kids in the car and changing the scene? Or is in the food itself? Because for me, one of my big weaknesses is the fact that I go to cafes to do all my writing, and of course there are awesome cakes and drinks and things there. So I decided I wouldn't do this anymore, and would set up a great writing area at home. But... later on, I realised it wasn't the 'going out for coffee and cake' thing that I was craving, it was the 'going out to write' thing. So now I'm trying really hard to not get a piece of cake or a brownie, and to get either a lite coffee (if they have it, which most of the time they don't), or a herbal/black tea. So this was quite a discovery for me.
One little thing that I have done is... instead of turning to food when I am stressed, I actually just file my nails. Weird, I know, but it really works. I file them, do the cuticles, sometimes even paint them - which is REALLLLY unlike me. But it totally works.
Hope it's going well, my dear! Keep us updated!
