Naomi, it probably isn't a massive help. But I'm also a binge eater, any emotion that isn't the norm and I'm straight away desperate to eat. Thankfully from somewhere I've managed to get some willpower and not go for my old favorites - biscuits, cakes and McDonald's. But I am conscious that it's probably still early days and I'm 'in the zone' so when that starts to slip I'll have a fight on my hands.
But... One of the biggest things I've done is found things which are low in SW syns, like space raider crisps, hifi's, mini flapjacks etc. If something has set me off then I tend to drive straight home after work and avoid all shops, grab a huge glass of fizzy pop to drink really fast, then I'll eat a packet of crisps and sometimes a hifi bar. Consequently I'll feel as sick as a pig and it helps stop the need for a bigger binge.
Like I say it might not be helpful to you and some people might be screaming at the screen but that is the best way I've found for me! At least it is something while you wait
