I love my coffee! I would drink it all day if it didn't bother my stomach, so I limit myself to two cups in the morning... usually. I don't like flavors in the coffee... just coffee. I used to doctor it up with cream and sweetener, but during periods of dieting and/or fasting I learned to drink it black. Now I only drink it black.
I've been noticing the last few months that coffee in the morning can mess up my vocal chords. I teach morning classes and need my voice! Sometimes the coffee makes it so I have to keep clearing my throat to get any volume in my voice. Don't know why... but it's annoying.
