I remember having a control solution for my first meter but not for my present one. That was my mistake so I will get the solution and check my meter. I also bought a second meter a few years back that was cheaper and got high test results, so I quit using it. I can correct that mistake, but really don't have much worry about high test results because the food in my house with the pandemic is low carb so I behave myself and do not over eat. I live rural and never left my home for 16 days this month, and my diet is pretty well controlled by the isolation. I quit baking Christmas cookies years ago because my grandchildren were not eating them. I have learned to refuse snacks from others without offending them so I am gaining confidence in eating well. Thank goodness the diabetes was discovered in the prediabetes stage so it has never been a big problem. My hearing has declined but that could happen from other causes over the years as well as diabetes. I am getting accustomed to my careful diet and look forward to the fresh veggies and fruit. Dorisena
