Aspartame hurts when i ingest it. But, we both know how bad it is.
All the other artificial sweeteners play hell on my energy levels.

Stevia... i don't die from it, but i do not feel right after eating something with it.
And fruit sugars have to be balanced out. Small portions over long time periods.

I really like molasses.
And something that really is good for me, but you might never think it, sugar cane juice. (you take the sugar cane and run it through a roller mashing the juice out of it)
