Don't do it cora, have a cup of tea or coffee with a few sugars thrown in instead? Or a bit of fruit - a sweet craving but healthier? You're doing really well 
I've done well so far today, I had a cuppa tea with semi skimmed milk and 1 sugar (trying to cut down on it slowly) and cornflakes and semi skimmed milk for breakfast, then I went into town to the jobcentre, then I did a bit of shopping and have done 2000 steps so far according to the fitbit. May take dog for walk later but it's raining and she hates it, so just sits on the pavement and refuses to move! Dinner was scrambled egg on 2 peices of toast, dab of butter, ketchup and grilled mushrooms and tomatoes. I need to weigh my food though, I just entered the toast on MFP but then thought the bread was quite small (end of loaf), weighed it and it was 60 cals for both instead of 180, so a close shave! I've had a cup of tea as well - semi skimmed milk and 1 sugar. I won't be cooking tea til 8 as DM's in work til 7.45, so I'll prob have a banana and fat free yogurt as a snack around 4ish. Dinner is a chicken breast (rubbed with garlic salt and basil) on the plate, pasta boiled and in a sauce of mushrooms, onion, pepper, tomatoes, tinned toms, passata and herbs and a bit of cheese on top and I'll have lettuce with it, I'll do bread and butter for the others but not me.
One issue I have is the evenings, I'm hungry in them and it's not just I want a chocolate hungry, if I eat tea at 5-6 I'm hungry by 10/11, and a cup of tea doesn't sort it out. I'm going to try having tea later, around 8 o clock ish because that'll see me through the night then. Also, I'm a lot more able to eat a banana and bit of yogurt at 4pm as a snack rather than at 9pm, when I think 'oh I've been good today, a treat won't hurt'and then eating a bag of crisps, a bar of chocolate, a handful of biscuits etc. I'm also trying to stop eating chocolate etc so much - easier said than done when parents come home with shopping bag full of goodies - but I'm going to try and have a little something every other day rather than every day - it'll taste better then if I look forward to something, and yogurt and fruit although it has a bit of sugar in, is probably better and more filling than a wagon wheel. I think I need to plan my treats and stick to them.
