Fascinating stuff. Thank you.
I understand the aftertase issue. I drink Zevia soda which is sweetened with Stevia. Nothing nasty in it such as colorings or preservatives. Very healthy. When I first tried it, I was put off by the Stevia aftertaste. But I persevered. After a week, my taste buds had fully acclimated. Now there is no sense of aftertaste at all.
Sometimes it may be worth it to keep trying.
I think you would really like the Lakanto Allulose/Monkfruit blend. It’s my favorite.
