Here is a good link that explains how to use Stevia:

I plan to use it for sweetener thanks to sockmonkey. I keep my sugar count kind of okay by taking a doctor prescribed Glipizide pill every morning. The more I can do to stay away from sugar the better off I am. I have copied and saved the info. on that link.
Since I discovered stevia I am sugar free except for holidays. I started weaning myself about 3 years ago. I drink tea black or with a squeeze of lemon.
Don’t drink sodas, unless it is a special occasion, and then I mix it with club soda or it tastes too sweet. I use a little unsweetened juice mixed with club soad when I get to missing the soda Fizz.
I used stevia quit a bit in the early days of weaning, but now I just use it when I make lemonade or something like that that is very tart.
