Funnily enough, I love my teas super strong (though I will get mine with cream and flavoring if it's part of a specialty drink.) But I can't drink coffee straight up without heavy cream or sweeteners because the acidity gives me incredibly bad stomaches a lot of the time.
I just love tea in general, though. Fruity/citrusy, minty, and green teas are my favorites. Also have this orange-vanilla rooibos tea that I love as well.
