Sometimes I don't mind it - I had a protein powder sweetened with stevia that I really liked. But I can't STAND it in tea, or in yogurt.
I used it in my coffee for a while and tolerated it, but it wasn't really better than drinking the coffee black, which is a heck of a lot cheaper.
If I got just barely too much in my coffee (any more than 1/3-1/2 a packet per cup) it was undrinkable.
