Groovee, you look Fab! So jealous of your boobs though 
Trills, re syns, you can save them up to use on occasions, but make sure you have at least 5 a day if you're going to do it. I've did that from the start and didn't affect my 7 stone loss. I even had a 52 syn trifle one week and still lost 2lb. As long as you don't go over the 105 syns in the week, you'll be ok. Life is worth living, and you can't be miserable in a night out just because you're on a diet.
I was at a christening today,and wore a non stretch dress (size 12), with really high heels. Felt fab. Before I lost weight I'd not have gone as was too self conscious about my weight.
