Hi Lily and Sharon, I switched from Cambridge to SW but not sure if I can offer much advice. With Cambridge I was stuck in a cycle of losing and gaining the same weight and then found I was gaining more than I was losing so realised it wasn't for me. I'm settling into SW well and have come to terms with the fact that I can lose weight but that it will take me longer, well longer than if I was 100% on plan cos the way I was going with CD I'd have never finished!! LOL All I can say is if you want to lose weight and are OK about it taking a little longer then go for it. I feel a lot less stressed cos it fits in with my life a lot easier, especially my social life! Good luck Vxx
