I have been talking the product for at least a week and a half now. I have never had my sugar out of the low 200's. That is with taking Metform 750 to 1,000 milligrams per day. After taking Curalin for a very short period of time My sugar is the lowest it has ever been- in the NORMAL Range! It is 110 after just taking it this eve which is just 10 points over what is considered very normal- I would say it is in the high normal range. I am floored! I will continue take and order this product! The only reason I am not giving it a 5 star is i want to see how it pans out after giving it a little more time. I wanted to give it at least a 4&1/2 but wasn't possible.
