New to the site and ready to change...my life!

My name is Brooke and I'm 26 years old. I have two lil boys, 3yrs and old and 18 months. I've since gained about 30 lbs since having my boys and I'm ready to lose it. I knew I had to get to that point where enough was enough and I am now there. I'm motivated and ready to lose the 30 lbs. but my ultimate goal is 40 lbs. I'm 5'4" and weigh 184 lbs, I would love to get back down to 140 lbs. I know it won't be easy but I'm ready. Very glad I had found this site
