I joined SW three years ago and lost two stone which was my target and of course I was delighted. It was slowish and took 9 months. I regained most of it so rejoined 7 weeks ago and its driving me nuts - Ive lost inches but its not showing on the scales! Im good as gold, stay on plan every single day and yet for the last two weeks Ive gained a pound! When I joined i was wearing size 16 and it was getting tight - Im now baggy in size 13. What the hell is going on???!!!
