Interesting thread. I think there's a whole range of "severity" of sugar addiction. As we can see on these forums, there are people who can't even tolerate artificial sweeteners without going nuts. Others, like me, can handle it. I put Heinz ketchup on my eggs. I can have a few saltine crackers with my soup. As long as we're not talking about a box of Oreos or something like that...

I also think it's possible for your symptoms to change over time. There was a time where nothing was too rich for me - heck, I'd eat cake frosting right out of the container. Not anymore. Once you start tackling the addiction, you also start to lose your tolerance. (At least I have...)
