It sounds like you are doing great. I would be more than happy with 8lbs. Even when I am 100% I have never been one of these people who loses a stone in the first week (and I begrudge every pound of it).
I lost 6 stone a about 3 years ago and have put it all back on. I have lost around 8lbs since the beginning of the year, but keep cheating. Anyway, I have ran out of excuses and the only way you can do this diet is to get into the zone and NOT cheat. It isn't worth it.
So from now on, not a morsal of food will pass these lips. It doesn't help that I only like tetras and bars so get a bit fed up of not having anything savoury. Anyway, I have gone through my boxes of size 12 clothes this afternoon, and despite the snow have packed a suitcase for my summer holiday.... assuming I will be back at size 12. Anyway, it seems to have had the motivational impact I wanted it to so all on board to go SS and not cheat once.
Anyway, fingers crossed it all goes well for both of us.
