Because the Lantus lasts for 24 hours, the way we do this is to back off one
unit of the evening dose the first night, and take a 1-
unit shot the next morning. A couple of days later, we reduce the evening dose by 1 more unit and add it to the morning dose the next morning, etc. until the right balance is found. Many of us do need to end up taking some Lantus at night so our sugar levels don't rise while we sleep.
