"Insulin Needs and Honeymoons
At first diagnosis, many people experience what is known as “the honeymoon phase.” The honeymoon or remission phase occurs after blood glucose levels have been brought under control and is characterized by a decrease in insulin doses. The length of a honeymoon period is variable (days, weeks, months, and rarely—years), and not everyone has one. As a general rule, the younger the patient at diagnosis, the shorter the “honeymoon.”
During the honeymoon period, the beta cells of the pancreas recover temporarily and start producing some insulin again. As a result, insulin doses are decreased. However, it’s important to note that the honeymoon phase is a temporary phenomenon and insulin requirements will eventually rise again."
