I have been taking Metformin twice a day for 2 and 1/2 years. It never really did much. I was really frustrated because I don't eat a lot of junk food, and I all but cut out bread and potatoes. A low carb diet didn't seem to help. My numbers went up all the time. I decided to try Curalin, and it actually worked! My morning numbers are great, and they stay great throughout the day. Even if I have something I usually don't eat, they stay in the normal range. I encourage people to try this out. It has literally changed my life. I am constantly chasing my numbers anymore.
