What KIND of diabetes?

Sounds to me that you are being treated as a type 2 Diabetic with you only taking the Lantus injections, this type of insulin never peaks, it just stays in your system for 24 hours and is meant to aid, in type 1 Diabetics, the fast acting insulin you take various times throughout the day, this is known as a sliding scale system for managing Diabetes Type 1. In type 2 Diabetes, Lantus is most likely used to aid what pancreatic function you have left, or if you are taking oral supplements to manage your Blood Sugar, the lantus will aid those as well. Type 2 WILL NEVER escalate into type 1. Type 1 is genetic, Type 2 comes about as a result of, most often, Obesity and sedentary lifestyle. Also, most often, Type 1 Diabetes is onset and diagnosed very early in age, however with your particular situation(the chronic pancreatitis) it could have developed from that problem. Hope this helps:D
