Well done that's fantastic. it took me 2 years to loose 15 kg's and although I still would have liked another couple of kg's, when I realised that I could fit into a smaller size of clothing it made me so happy.
Don't loose faith, sometimes all you need to do is stop thinking about the loosing weight, and focus on the healthy living give your self a couple of weeks of that and then return to the close scrutinizing of counting points and weighing in. It's also a good test to see how you will go post WW.
