Hi Kimmi --
When I did LL one of the women in the group said that she was saving money (and that was 66 pounds a week), because she wasn't drinking, going out, eating out or having their weekly 40 plus pound Indian takeaway. She was clearing cupboards, cooking what in the freezer and only buying what she needed for her family's meals not stock piling food.
Congrats on the loss -- you are nearly in the next stone bracket!
