Loosing 100 in 3 yrs! Add me.

I'm a married father of 4. Recently went to my second youngest's graduation and had a reality check. My goal is to loose 100 in 3 years. I not only want to loose the pounds, I don't want ever to see them come back! It's a lifestyle change that needs to happen. I was at 300. Now at 295.5 and jazzed that I won't see 300 again, ever. Looking for friends for mutual motivation.
