down 25 lbs and 2 jeans sizes....50 more lbs to go

Im 44, a nurse, the proud wife of an iraqi war veteran and the mother of 2 beautiful children ages 21 and 19. Aside from the fact that I now have an empty nest, I am dealing with the daily appearance of yet another gray hear( silver as my mom calls it) and the metabolism of a snail. I am doing well though...counting calories and exercising daily. My goal is to be down to my goal weight by July of 2012 when we go on vacation.
