[hmschoolmom3]

I am planning on starting this monday. I need to loose about 40-50 lbs. I am tired of being overweight. How do I start and then how to keep it going. i like to go out to eat with friends especially Mexican. Husband has been mobilized with the U.S Arny since May 2006. We do get to see Him often and He has not had to go to Iraq yet. I have 3 kids and I home school any wisdom for me while I am in this particular season of my life.
