Ah yes, the birth control...hormonal...battle. Im so glad my doc let me go off mine. They can definitely be evil when it comes to weight loss !!! If you cant have the surgery now see if Doc will let you come off of it. I know how you feel with losing so much in the beggining...then slowing, Im in the same boat. We just have to keep plugging along....at a slower pace...but still moving in the right direction.
Your progress has been great !!!! Im sure anyone who sees you that hasnt seen you in a while will notice a difference wether its exactly the weight you wanted to get to or not. :)
