Chocolate

I've determined that my problem is not sugar in itself - it's chocolate. I, quite simply, cannot function without it.
I have tried staying home for entire days with my child, and if the chocolate bus starts buzzing - satisfying it with greek yogurt and honey, or a popsicle, or whatever else kind of sweet is in the house. But by the end of the day, I'm like a crack addict without her crack and I'm spending the whole late afternoon/evening trying to come up with an excuse to go to the store and get some.
Many days, that there is no chocolate to eat is a good enough excuse.
So, here's what I'm thinking. Keep chocolate in the house. Sounds easy and terrifying, right? What if I do it this way....
I jones for my fix especially during H's naptime and in the evening after she's asleep. So, what if I allow myself a bit (no really, a bit - I can't honestly allow myself a whole # each time, can I?!) at both of those times. I can buy a bar (or whatever) a day, and split it between those two times with a gigantic glass of water. What do you all think? Can I make it work, appreciate the tiny indulgence to prevent the monster addictive binges? Thoughts?
