Buying the 2012 food directory, low syns book and free foods book.
I'm doing it from home with a members pack, and not finding it too difficult as I'm very self motivated. But trying to find syns values online for some more obscure things was driving me nuts!
I debated it for ages, the books are £30 for all 3 on eBay (more than double class prices!) but then I thought hey I have 95lb to lose, it's going to take me about 18 months at least, so £30 is a small investment really!
Wish i'd done it 11 weeks ago, life is so much simpler now and so much inspiration to be found!
