Firstly, to answer your question immediately - DON'T QUIT. Now we will explain our answer. Diabetes is a disease affececting how your body makes insulin and how it uses glucose (sugar). Insulin is a hormone that helps your body use sugar by allowing the sugar to enter body cells. Type 2 diabetes occurs when your pancreas (an organ that lies behind the stomach) has trouble using insulin or is not making enough insulin. The goal for diabetes is to keep your blood sugar normal and controlled. So clearly in your case your body needs the lantus (insulin) in order to keep the sugar at a normal level. By discontinuing the lantus your body will accumulate all the sugar in the body (since your body is not making enough insulin). Temporary hyperglycemia is often benign and asymptomatic. Initially, you will find the following symptoms which are not as serious such as being frequently hungry, thirsty, increase in urination, fatigue, blurred vision, and dry mouth. Blood glucose levels can rise well above normal for significant periods without producing any permanent effects or symptoms. However, chronic hyperglycemia at levels more than slightly above normal can produce a very wide variety of serious complications over a period of years, including kidney damage, neurological damage, cardiovascular damage, loss of vision, and so on. In diabetes we are always trying to control the sugar levels to a normal range. As a recommendation I would not quit insulin. If you are having some sideeffects from Lantus there are many other options which can be discussed with your physician. Quitting is definately not a safe answer.
