I find thata major sweet tooth at TOTM.
So I survive on loads of sugar free jelly, sugar free lollipops, and a bucket of painkillers!
And if a big craving hits me I come on here and chat, or look at the inspiration slideshow.
You should def. try a bit of exercise though, even if its just a walk down the road for 5mins, can help lift your mood a bit and make you more positive.
But as Gg said it is just a hiccup, and we'll all make mistalkes along the way.What matters is whether you let it get you down and give up or dust yourself off and continue.
Good Luck!
