Hey there, sorry to hear you are having such a struggle at the moment. Think it is a combination of lack of water, peeping at the scales and this flippin cheese thing that is going on at the moment. Take a big step back and look at what you are doing. You're just making it harder for yourself. Bin the cheese, with fairy liquid over it and refocus, refocus, refocus.
Come on here as much as you can, join the Let's do it Hour by Hour thread and pat yourself on the back for every single hour you SS perfectly. Next thing you know, you will have done a whole day. Then another, and another, and before you know it, it will be weigh day and you will have a loss! You cannot fail to lose if you stick to this diet, so don't despair, don't peep, have faith. Little steps!
Good luck
