Shame on me...

Yesterday my parents gave us a visit... Lunch was ok, as I was on PV... but in the afternoon we had some coffee and a chocolate cream cake... well my son (18 month) ate almost all of his piece and I just ate the tiny little rest. Quite ok? Or? I mean I did not eat any sugar, sweets etc. since I started the diet. One and a half week without sugar is a big record for me.
