Lisa, I get it at the local health store. Just so you know, you don't need to use a whole lot, excess will make it taste a bit bitter. . It is actually an herb.
I use splenda and I reccommend it. I have not tried your products and probably won't unless they become as accessable, as cheap and taste good enough. If it aint broke- don't fix it.
Yes, I use Stevia. I want only the best for my body! Stevia tastes just as good as sugar or splenda. I'd rather take the healthy approach so nothing gets broke.
