arrrghhh I've just ruined my entire week I'm a 1lb away from the 9's and I may have jepadized this

I've had a total of 38.5 syns all week trying to be good as we have a big party Saturday night and there will be lots of drinking ! and today I've just had a Burger King with my son

a wrap and chips about 45 syns its something I never do and I really fancied it I feel sick it's sitting in my stomach like a lump of lead and it's not happy

thankfully my hubby has alway had a large lunch and doesn't want dinner tonight ! it's carrots sticks tonight !
