Setting aside "good health" etc, what are you giving yourself, if anything, as a reward for losing weight?
In 11 ounces' time, I will have lost a stone (14lbs). I've decided to mark it by buying a Trollbeads silver bracelet (oh, that I could afford the gold!) and one nice bead. I've promised myself a new bead for every stone. It works out about GBP2 per lb for the beads.
It will actually be 3 stone from my highest ever, and I've decided to add beads for the previously lost 2 stone right at the end. I want to look at each new stone/bead and savour it!
