Congrats on 31 days.
Sugar is like alcohol for me in that if I eat it, I want more. If I abstain, I don't have cravings. And that is hard to do for sure. I've put on weight since Cookie-pocolypse at Christmas. Its a work in progress for sure.
I was wondering if some kind of more structured program might help you. There are meetings where you can take kids. Especially woman's meetings. Or join gym that has daycare. You can drop the kids off and get a couple of free hours exercising. That was a life saver when my daughter was young. Really helps with that irritability and pent up feeling.
