time to get back my life & health

I am looking to loose about 60+ pounds. Just found out I am pre-diabetic and have a few other things going on that loosing weight would be a benefit. I have a 3 and 6 year old and want to be around for a long time. Like everyone else I have lost the weight before and have put it back on and then some.
I also saw about this site on the Today Show and thought why not give it a try. I need all the support I can get. it seems to get harder and harder as I get older to loose the weight.
For now I am taking it a step at a time and starting with trying to loose 10 and then continue from there. I want it to stick this time and not continue to ride that weight rollercoaster.
