I am now suppose to give up sugar (I have been diagnosed pre-diabetic) as well and that was hard but no longer put it in my coffee (3- 4 cups per day) nor on my breakfast cereal and I buy a no added sugar cereal. I do however eat a lot of cakes and pastries and a crepe with lemon and (brown) sugar is my big treat at the Farmers market on Saturday morning.
I have given up sugar in the past and found it pretty easy after the first week or two -- I just lost my taste for it. Once I start eating it again, the sweet tooth comes back, but weaker than it used to be.
I've never used it in coffee, I've long preferred sugar-free breakfast cereals. I like cakes and pastries, but even those aren't the temptation they used to be. When I eat in a restaurant, I never even look at the dessert menu -- not out of restraint or self-discipline, but because I'm just not that interested.
However, when people bring cookies and donuts, etc., into work I have trouble passing by them all day without trying some. Lucky I don't work in Chuck's office!
