So, I like to sweeten my coffee, and I bought an organic stevia product to put the brakes on the sugar. Yuck! It has a bitter aftertaste like saccharin. Then I bought a pound of dark brown sugar to pair with stevia. I've been adding a couple teaspoons of sugar to my coffees for a few days. Result? My knees ache after sitting crosslegged again! I didn't have any joint pain during my Whole30. Scary.
