Hey Katie, i need to lose about 20kg as well. Its hard when theres such a long way to go!
I havent been having huge success with the scales dropping on me, but i have toned up...have lost 21.5cm in the last couple of weeks. Its worth taking measurements if your not already, because anything that can encourage you will keep you going!
Personally, my encouragement is the fact that my husband cant seem to leave me alone at the moment! sometime i think it might be dangerous to my personal space to loose anymore!!!!!!!!!
