Chromium supplement might well work, I don't take it since going prima, but it really used to help control hunger and feeling low on blood sugar and then going and eating a whole pack of chocolate covered hob-nobs 
Totally agree, as an ex sugar addict you need to go cold turky - when you get hungry go for something fatty, and make sure your meals are not too low on the fat, stick some butter over your veg, make sure you are using fatty cuts of meat in stews, and if not stir something like sour cream - works wonders on a beef stew.
It took me a while to adjust my thinking to eating fat, but it really helps satisfy you and keep the munchies away - and if peanut butter is your thing I suggest you change to sugar free, tesco own brand is about the cheapest I've found, and use a spoon to deliver it to your gob rather than a slice of bread, I find a spoon full is a great snack - with a few berries if you have them to cut through the claggyness
You know all those pictures of Adam and Eve where they have belly button? Think about it..................... take as long as you need........................
