I did SW in 2005 and got to target. Kept it off until 2009 when I became ill. So far am finding it very easy with the changes in the years between. There is so much to eat and have found my mojo for cooking again.
I tried weight watcher but I couldn't get my head round the plan. I like that I only weigh cheese/ milk or bread/crackers/ cereal and don't need to constantly be weighing.
