You're lines above say it all. It does have to be a whole life change. With that attitude you'll have no problems. WAY TO GO!
Always remember to take things one day at a time. We always have choices. We can choose the apple or the Twinkie. The power is our own. If we just worry about making a good choice in the moment... the pounds will disappear on their own.
I just wanted to wish you good luck with you goals. All you have to do is believe in yourself and things will start to happen! Get support from Spark Teams because people can give you great ideas. I started a group called Art & Craft Ideas that I run with a spark friend ... so please feel free to join if you have an interest!
