I have had issues with Aspartame...its hard to describe, but I become physically addicted to it, always needing more...and walking around in a ‘funk’, while jonesing for my next aspartame fix. I’ve been hooked twice, and quit twice.
So I’ve been reluctant to try another non-sugar sweetener...but I might give Stevia a try.
A friend of my wife’s worked on Aspartame when it was developed—he said the physiologic effects in the human body were not all beneficial. He would never ingest it.
Stevia is a plant product. It is very sweet tasting, however the taste and quality varies dramatically between producers. My wife uses NuNaturals NuStevia. It is available online and also at GNC.
