weight gain and post op

Options
Hi, I am a thirty year old mother. I recently had knee surgery and gained 20 pounds in a few months! I was already overweight, so this was definitely unwanted! I have been up and down on my weight for years and I hope this is it. I wanted to join this site because someone I know recently lost a lot of weight using it. I am looking for support, and hope you will add me so we can support each other!
