Sarah ~ I have just started as well (Today is Day 1 of the food!)
First, as an Army vet myself, your husband and every other soldier willing to sign up to fight for our country are always in my prayers; I will say an extra one for him (will call him Sarah's husband!)
I think Jan is right, that you can lose 50 easily by then, as long as you stick to the plan (that may be rough through the holidays) but Nancy has a great saying "Nothing tastes as good as thin feels" that I love!
The studio is a GREAT resource for inspiration -- it is what made up my mind to use this product over others. You can see the before and after, and as soon as I get my "before" pix developed, I will send them to Unca Tim to post them -- I personally think that is a GREAT way to hold yourself accountable. Of course, everyone is different and you may not want to do that.
We can help each other out in the beginning if you would like! Hope this helps ~
