Sorry to hear your bad news, basin and lemony.
Only 1/2 off in my second weigh in, but I'm trying to be philosophical about it. I've lost half a stone in the first two weeks. Not sure what went wrong in the second week - actually, we had a bit of a get-together with family at the weekend and I drank far too much vodka
but food wise I was pretty on plan.
BUT, I'm a tax advisor, so loooong hours this time of year. I usually never start dieting until Feb for this reason and rely on takeaways, sweet treats and bacon sandwiches which the partners buy us in the office to get us through. So, rather than 1/2 off, I'm trying to see it like at least I've not put my usual 3-4 lb on which is what I would have done had I not been on SW..so it's almost like a 4.5lb loss 
Todays plan:
Brunch - two slices wholemeal bread, which I'm actually coming to not mind, with beans, poached eggs and mushrooms.
Tea - SW chilli, poss cauli rice but if I can't get to the shops I'm going to have to think of something creative for speed! Maybe some roast peppers.
Basin, absolutely agree with you. There will be times when I have a 'fuck it' day. These will be planned, rather than spontaneous like my previous 'fuck it days' but I won't be ordering boiled rice and worrying about how much oil is used in the the cooking!
