Posting this retrospectively having decided that this would be Day 1 (see here for more information):
#1 13 st (182 pounds)
Any weight loss will knock me into the twelves and anything more than two pounds (as if) will land me in the 170s, a happy (or at least happier) place indeed. Fourteen weeks post-partum saw me at 12 st 8 lbs (176 pounds) and I look forward to shrinking beyond that.
First Goal - to lose something and put myself in the twelves once more
Reward - ironic I know but a bag of peach loop sweets (twelve sweets only though)
