I have fibromyalgia and find that sweeteners really make my joints ache and I have more attacks when I use them. The latest being Stevia. After the first week using it, all the aches and pains were back, I quit a week and I am not aching and not feverish, no flu symptoms. I no longer drink soda (addicted) at all, and I want to drink tea. I think green tea would be the best way to go, but I truly can't stand it. This morning I started Truvia. I did just use regular sugar for my tea last weak. Putting in a teaspoon isn't that many extra calories and I didn't have any side effects. If Truvia doesn't work for me, I will have to start adding about three teaspoons a day to get my tea fix. Anyone have any information or ideas for me? Thank you.
