Good for you for finally taking over your life! I suggest getting on this website as much as possible, it really helps having a support team! There are a few Nutrisystem forums that I'm sure you'll like also! I personally havn't bought Nutrisystem but I have tried a few random things that I had purchased at Big Lots store. They were good. I have heard great success of Nutrisystem though!
Here is the link for Nutrisystem buddies:
