I stay away from all artificial sweeteners, but have recently started drinking an antioxidant drink that contains Stevia. I love the drink it tastes delicious and gives me extra energy while boosting my immune system. I have noticed since starting this I am having issues with numbness and tingling in my feet. I stopped drinking it for awhile and the numbness went away, I have recently started this again since its flu season and I don’t get the flu shot so I wanted to keep my immune system in check and feel this def helps, however the numbness and tingling has returned 🙁 .. I am going to have to stop it again! I see in this tread that other people have had this issue as well with Stevia.
