Weight watchers

Today i joined weight watchers. Im currently 160 pounds. I want to get down to 115/120 again. My height is 5'2". I NEVER weighed this much!! The reason why i want to loose weight is because i cant fit into ANY of my clothes, including my bras and panties. The reason for my weight gain is because i overeat and i have very large portions. Also i drink wine or liquor everday. Im very excited about this. Today im going out to buy a nice scale.
