Just to add insult to injury, I was expecting an order of bars from Exante today.  Needless to say they arrived during the half hour I was out and I cant guarantee being in again all day until next Thursday.
So Im afraid I just caved and had a low carb cake.  155 calories, 12g carbs so could have been much worse especially since I havent had a second pack.  Still slightly gutted with myself but I needed to physically eat something, Im getting sick of the sight of liquid.  It was a very strange taste sensation mind you.  Lack of sugar and flour makes a very odd cake.
