Thanks so much for all your replies.
I have taken many of your points on board.

I have been having a hot choc every noght which i think is contributing to the problem... I mug of skim milk plus ovaltine is a big wack of kj... i will have a look at something else to replace this as i think this really is where the weight is coming from (and the snacking that goes with it)
I have not bought any biscuits or lollies for a while now - DH keeps coming home iwth them though, its hard for him though as he has an extremly physical job and an incredoibly fast metabolism, so needs to continually eat to keep weight on wish that was my problem!!!

I also made a massive fruit salad yesterday, so will have a bowl of that if temptation arises.
Have tried to keep busier in the evenings too.

I also have noted that the days that the temptation ios the strongest is also the ones that i am exceptionally tired - maybe i want to snack to stay awake (sugar kick for energy) when really i should just head off to bed early. Will also try this me thinks

Good points about the hungry vs bored snacks - i am totally NOT creative and everything i try just turns to poo - knitting is a disaster and yeah, would love to try MCN's but dont want to waste more money on material that will never really get used as i will give up after it wont work (thats sounds really really negative, but i am one of those types that is just not good at creative stuff)

Thanks again everyone, it so nice to know that i am not alone!
