Night or Day Lantus

Hello
It is a question that is undoubtedly answered in previous messages, but as I am new, no idea

After so much years, the change of habits undoubtedly induces errors, and that has passed, dose in the previous night, of the new pattern (24 units) and usual dose (18 units) was put in the morning, go mess.

We will adjust 6 tonight and tomorrow we will do what the doctor has put, 24 units x the night.
Does it make sense to change at night?What will it be based for it?Do you know?

At night it can produce hypos and, if the dose is lowered, it does not last 24 hours.
That is why it is usually better to put it in the morning.
Although there is Alba phenomenon, then better at night.
You have to look for personal schedule

Thanks Regina.
