Dont worry small steps Keen!
Every time you feel the urge just try and distract yourself - coming on here and reading the success stories here can help!!
Also try not to keep kids snacks in the house - if i know i have to get off my bum to the shops to go and get a chocolate bar (esp in this weather) i know im too lazy!!
Another trick is to exercise first thing - then you have a little buffer if you dont manage 100% AND most importantly once u have done your exercise and the guilt when u do cheat is massive and keeps me on the straight and narrow - i think whats the point in doing all this exercise and then ruining it with this chocolate/crisps!
If you need to put something in your mouth try making it a small bit of protein - some ham or chicken or something - much better than chocolate!
Im a re-re starter too - lost 3 stone on LL a year ago and put back on!! Lost a stone so far (on atkins) but am back to exante as i need to see movement on the scales or i get disheartened!!
Good luck and keep posting - deffo helps with the motivation!!
