I have some stuff called Truvia, not a big fan, it says it's made from the stevia plant, I think I'm going to take it into work and put it by the coffee pot, maybe someone else will like it.
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.
Tastes a bit grassy to me, but I've gotten somewhat used to it in my coffee. Bought a box at the discount grocery store and am determined to use it up before switching back to splenda.
I use it combined with Splenda or Sweet n Low. If you put them together it enhances the flavor and sweetness. Then, I use less packets overall. Since certain brands/colors are cheaper its a win win...saving money by using less packets and less expensive colored packets. I don't notice any bitterness if I use 50/50 splenda and stevia.
