I'm at a loss

Yesterday, I ate oatmeal, and brown rice, and fruit all day - no soda, just water and a cup of coffee.  I had to leave work and go straight to New Horizons Academy in Blaine because the wife wanted to check it out again to make sure baby D's current daycare is the right decision.  I'm pretty sure that after our tour that she felt it was too institutional and wants to stay in the at home setting she's currently at.  It was getting late and neither of us were in the mood to cook anything, so we decided that I would swing into a fast food joint on the way home and pick us up a couple of grilled chicken sandwiches without the mayo -- not a perfect meal, but still much healthier than the Triple Angry Whopper (seriously a new item on the menu).  I ordered up the chicken sandwiches and some diet cokes and I swear to God, I had a 99 cent double cheeseburger ordered and down my gullet before I could even think twice about it.  So I gulfed down the burger and drove straight home, like the drone that I've become, and ate my grilled chicken sandwich pretending that it was an adequate meal -- kind of ironic that as I finished my fries (of which I convinced the wife were ok to order because we ordered the chicken and I'd eaten good the last couple of days) that the Biggest Loser theme music kicked in.  I'm no longer a weight lifter, certainly not a runner and I love to eat and drink -- I'm completely at a loss of what to do!
