Don't know if it's "acceptable," but my husband and I are on round two, a year a half after round one, and have had no problems using a good bit of it.
To us it just tastes better than all the other Stevia products, which seem bitter and leave a chalky film on your teeth.
I used it on my second round and had a hard time staying on the diet. Now I am i week into my third round and thne struggle is beginning again. I am looking to see what I changed....
I have been using Stevia and Truvia...actually I use the flavored stuff.. I dont see any difference.. actually in my paperwork it says to use it as the sweetener of choice..
