On day 8 I had a chicken salad and I felt absolutely awful - I ate it and as I was eating I felt guilty and remorseful yet still kept going. When you know you shouldn't be eating something it really doesn't taste so great. I know it's hard resisting stuff, but honestly when you have your weigh in you will know it's worth it. Perhaps you should try and occupy yourself - paint nails, do some washing up, clean the toilet! - anything to distract you from the sandwich!!
