Hi Sara, you may find my experience with sugar helpful.
When I was young, I used to take lot of sugar. This was purely because I grew up in house hold where sugar is consumed in large quantities and I never knew any other way. I used to take about 2-3 spoons of sugar with my tea and coffee. One day, when we were having tea at work, one of the colleagues commented about my sugar intake. She said, the problem is that I have never tasted the coffee or tea as I drink syrup. My tea, coffee or chocolate will taste the same. I agreed. So I gradually started reducing sugar. Over one year, I stopped taking sugar in my drinks completely.
It had effect on other food stuff as well. I now can't eat icing on cakes, dust off sugar in doughnuts etc.
So my suggestion is that, take it slowly.
