Hi there!
I would say GO FOR IT!
I love SW...it took me a little while the first time round to get my head around the plan, but after a few days of Food Optimising it is so easy to do. It's even easier now with the Extra Easy plan. You basically have Free foods - foods you can eat freely with no measuring, weighing etc - everything from pasta to rice, bacon to chicken. Then you have healthy extras - which you choose 2 of a day (if you're on Extra Easy) - these give you calcium and fibre. Then anything not included on those two lists are your Syns - if you buy a Directory you don't have to work them out - it's all done for you! There is a Syns Calculator on the SW website too.
Out of all of the diets I have tried, SW has always given me the best results, and the widest choice and variety without the hassle of weighing and measuring.
Hth! x
