Sounds like you are putting your foot down. It's a great feeling to be in charge of yourself. You are on the way to better health and freedom. You are an inspiration to all of us who need to do the very same thing. Luck has nothing to do with losing weight, so I won't wish you Good Luck. However, I hope you stay strong and not let anything get in your way of reaching your goals.
Congratulations on your important step!
