Absolutely, I have done SW for more or less 7/8 years but found myself getting into bad habits so I went back to group two weeks ago, I only have 10lb to lose and managed a 3lb loss my first week! once I lose the 10lb I will be back to a size 8 so even if you don't have a lot to lose like me it's still working for me and I have still been going out of a weekend so I'm not even being 100% either! I am however mixing it up a lot more now I'm back at group and have got lots of new ideas, I follow the red/green plans though not EE.
