Many people who need multiple daily insulin doses cannot safely stop insulin, but in some cases, doctors may reduce insulin or combine it with oral medications after careful evaluation and monitoring of blood sugar levels. You should never change insulin on your own. Erectile dysfunction is common in long-standing diabetes. It can happen due to damage to blood vessels and nerves, stress, or poor sugar control.
