I carry a little box of sweetners in my massive sack of a handbag, I know what you mean, sugar is such a waste of syns. I feel better for having a red day too... but still craving a nice crispy jacket potato and beans. 
 
I think we're green girls at heart. 
 
Ohh... my biggest life saver has been a huge bowl of chilli in the fridge, that way I just hit a bit up in the microwave when I'm hungry. 
 
Have fun at your friends xxx Birthday cake tastes of poo anyway x
