I have an admission to make 
I've not - and don't expect ever to - got over enjoying sugary "treats" - like a Peppermint Crisp (South African bar of chocolate - like an old-fashioned Mint Cracknell), a creme egg, Toblerone, my fantastic
tablet, a nice cake, a slice of my home made sour dough bread - either toasted or warm with a slathering of butter 
and even a croissant or pain au chocolat

However, what I have been able to do is put those desires into a box. I can walk into a petrol station and I don't even look at the rows of sweets. I have a stock of Peppermint Crisps that my dad brings back from his trips to SA that I am able to forget about most of the time . I can make chocolate chip cookies for ds' rugby team and not have a single one. I can put 30 pieces of tablet into a bag for my dad to take to SA or for dh to give to a tablet-loving friend who is going a tough time actually that last one was tough 
What I tell myself is that I have to really want it - and most of the time I don't. My motivation to lose an average of 1+lb/week is stronger. I'm keeping my long term goal at the front of my mind, rather than a short term sugar or carb fix. 
These "treats" will still be around in years to come. I don't need them now.
Long term, I'm trying to remind myself that the French have wonderful patisserie shops but don't gorge themselves all day, every day (unlike the way that we in the UK eat sugar). Patisserie is an occasional treat - and that is the way that I hope, once I've reached target, that I'll be able to factor in some of the things I've talked about above - but only if I can maintain a healthy relationship with such "treats".
Now I'd better go and drink some water
