I give myself until October 20 to  get down to124. My reason for going on the diet because I have been strugglin with my weight and now it is time for me to be for real and get my life back. I really dont have a problem losin the weight but since I got married  I have pick up a couple more pounds and i really want to get back down. so anyone who is readin this you can leave some advice
