I switched to Truvia (from Sweetia Plant in Central America, and widely available in supermarkets), years ago, and it got me off insulin, and on to Metformin.
.
I am using erythritol - (which is like Xylitol) an alcohol sugar (byproduct of fermentation)
with no side effects.
I also use monk fruit extract - all natural - it is sweet
but the sweetness of it is NOT from sucrose (like sugar). I also use stevia extract - from the leaves of the stevia plant.
Likewise, it is sweet without containing sucrose.
The human digestive system doesn't recognize the sweeteners in them -
and just passes them along.
There also are blends of of monk fruit / stevia and erythritol
which are both available in my supermarket and they are what I use:
Good Luck!
