I have been taking Curalin for about 3 weeks now. I was on Metformin and still had blood sugars between 130-150, so not super high but still over where it needs to be. I heard many good things about CuraLin and decided to give it a try as Metformin is not the best medication, with the side effects it has. I tried it on day one without taking Metformin to see what it was like by itself. My first morning my blood sugar was 129, already better than Metformin. And it went down from there. Since that first day, I have not had a reading above 110 and usually between 80-90 depending on how good I eat the day before. This has been a life changer for me.
