I did the same thing, and it is funny cause now that I only drink sugar-free coffee I actually enjoy it much more!
And I'm also able to tell difference between good coffee and bad coffee cause there is no sugar in the way hiding coffee's taste.
I once complained at the office that we were out of sugar at the coffee corner, after same asking around, I found out that I was the only one in the office drinking coffee with sugar. That meant I alone consumed the entire box (1500 portions of 5g) of sugar... A collaege gave me the best advice ever: "It's all between your ears, stop with sugar and within a week you'll no longer mis it". He was right.
