I do not use sweeteners for my coffee and tea for sometime now. I got use to the real taste of coffee and tea. It's just a matter of conditioning your taste buds. Only now that I have this sore throat. I use honey with lemon to sooth my sore throat again.
When I drink milk I add honey and sometimes sugar (I drink goats milk and it is sometimes quite bitter on its own). When I drink tea or coffee I add half-spoon sugar which I THINK is a mixture of sugar and sweetener but I'm not sure...I just know it has half the calories xD I don't tend to add sugar to much else, I have the same sugar as in my tea on top of my cereals and I like to cook my carrots in a mixture of butter and brown sugar, but that's just because I'm weird.
Depends on what I'm making. Lately I've been making my coffee with honey in it. However my oatmeal has white sugar in it. If I had brown sugar, I'd probably use it in coffee or oatmeal. I never use artificial sweeteners because I think they taste horrible. Also, my husband is allergic to splenda so that's automatically not used.
