I know that feeling Karena, I have a sweet tooth myself. I try and not buy them....but of course one occasionally weakens and you buy something knowing your being naughty in doing so. If I have a box of Malteasers, they will all be scoffed in one evening, same with a packet of biscuits, so I try hard not to buy them in the first place if I can help it. (Easier said than done)
Same goes for my weekly shop, I often don't go shopping some weeks, as long as I have the basics in of course, I've started using long life milk now, as it was going off before I could use it all. IOW if it's not in my fridge/cupboard I can't eat it...lol
I've been living on toast or porridge for breakfast and Baxters soups all the week for tea, saving me money too.
For a treat I'll open a tin of fruit. It must be working as I've lost over a stone since the Leeds meetup, I shall probably plough it all on again over Xmas....be fun doing it though..
