Pete,
You have to have something to give you a bit of a light at the end of the tunnel, otherwise you will start to crave for it, and you may succumb to the odd choccy bar or ten.
When I was diagnosed, I just switched over to artificial sweeteners straight away (the ones I use are called Sweetex, about 1 pound for a couple of hundred doses). Once you get used to the slightly different taste, no more sugar craving. I also use the powdered stuff on my cereals in the morning. Now, I can't stand the taste of real sugar, it is just too sweet.
Even though my house is full of choccy bars and sweets, for when we have visitors, I might have one very small bar about once a fortnight, as a treat for being so good. Don't for goodness sake buy anything that says DIABETIC on it, not only does it taste like crap, it doesn't do you much good either.
BTW, nice chatting to you on Skype.
John
