I am taking a diabetes self-management class for T2 on insulin. There are several people in the class that are not new to diabetes. I was amazed at how little some people with diabetes know about the disease and how to treat it. People with diabetes who are using insulin really need to be educated about the use of it. Most doctors do not have the time to sit down and explain the ins & outs of insulin. Insulin is a wonderful drug to treat diabetes, but I think that it is a drug that needs to be customized for each individual and this takes time and is best explained by a doctor, nurse and diabetes educators. If you are new to insulin, do some research on the use and how to make the most out of the regimen you are on.
