How are you doing?

I'm still addicted to stevis instead of sugar, and I'm having severe joint pains in my knees and ankles that make my feet have pins and needles, numbness and pain. I'm thinking it's the stevia again. I'm having a hard time sticking to a sweetness-free diet, but it looks like if I want to be pain-free I'm going to have to. 
Are your feet OK now? Do you use any sweeteners? 
This is an old thread. I hope you still get this.
