Since starting with Curalin I found it so effective that I replaced my prescribed Metformin with Curalin completely. So pleased to come off Metformin which I hated because of side effects and longer term potential impact on kidney function etc. Curalin being completely natural has no such side effects and has been keeping my blood sugar levels at safe levels - its proved more effective than Metformin in this respect. I am extremely pleased with Curalin _ I wish I had discovered it many years ago. I continue to exercise and be careful with my diet and in this respect I check my levels very regularly as the Curalin is so effective in keeping them stable. I have just received my second delivery of 3 bottles, very timely dispatched by Curalife and although it is obviously much more expensive than my prescribed Metformin I do not in any way grudge this because of the quality and effectiveness of the product. I guess I am helping the NHS in a small way by not having any need for further prescriptions for Meformin! I remain one very happy customer of Curalife and have no hesitation in recomending Curaline to other Type 2 diabetics currently prescribed Metformin. Please do give it a try.
