Dan this isn't something you can't deal with. At the end of the day the worst case scenerio is you're out some money.
The COD didn't lose this weight, you and liz did. They showed you the way but YOU did all the work. Deviating doesn't hurt them, but it absolutely hurts you.
I too would be livid if I were you guys, however, what kind of statement will you be making by gaining weight? How will that solve your situation? You know it won't hurt them but it will surely make you feel like a worthless piece of crap.
And on a final note, you "old timers" are an inspiration to those of us who are just starting this journey. There is a light clearly shining at the end of your tunnel. GO TO THE LIGHT LIZ AND DAN.
This is just a rock in the path of your journey. Go around it and give it a go to **** look as you pass. But get around it!
We're behind you 100% here and will do whatever it takes to get you thru this. You DON'T need the COD, YOU have everything you need to be successful.
Pick yourself up, shake yourself off, go and sin no more.

Consider yourselves hugged
