@73kittycat73 - You go for it, you deserve a blast for all the hard work you have put in. If you have been dieting and losing weight since February, I doubt a few days blast will make a lot of difference to your weight to be honest, it certainly won't undo 5 months work, that's for sure! 
On that note, I too am going to treat myself. Had the weigh in this morning at SW, 1lb loss for the week which I am pleased at because not only did I not maintain, but it gave me enough to get the 1.5stone award. They also remarked on how I had loss the weight in 8 weeks, and how my clothes were just hanging off me 
Total weight loss so far is 24lbs, and so I am going to have a chinese takeaway tonight, however, I will not be having all the usual dishes, I will share one meat and one rice with my wife, and so probably 35% of my normal scoff.
@WheresMyTweezers - Good advice thanks, and well done on losing that pound. I like your goals too, and don't ever feel you need to tell anyone about your starting weight, it's private to you, but also don't beat yourself up. You are tackling your weight concerns, you are doing so well, and that deserves a sticky star 
Oh, and another thing. I have dropped from an XXXL clothing size to an XL. To be fair, the XXXL were very big even on me, but that was the only size I could comfortably wear. Over the past 8 weeks I have lost 24lbs, but also lost a good amount of inches around the waste etc, allowing me to fit into size XL comfortably, I can even wear size L, but it is a stretch. I am not very tall though, just 5ft 8in and so all these large clothes look ridiculous on me.
The heaviest I got to before doing this diet was 19st, and now I am 16st 8lbs, a total loss of 34lbs, hence the XXXL clothing. I am only taking into account the loss since starting SW, hence 24lbs loss.
@picklemewalnuts - How are you?
