I can't stand sweet coffee. I take mine just cream, no sweetener. (Although, I do occasionally partake in the flavored creamers, but it is RARE.)
I find adding sugar to hot coffee makes it bitter or funky tasting. (Unless it's like a frappuccino, where it's a cup of fat and sugar with a dash of coffee. I like that just fine!)
I get the natural coffee mate sweet cream flavor when I want sweetener and flavor... Which is very rare. (Or if I use the creamers to flavor cheesecakes and have leftovers.)
