Under the dose or not?

Hi, I'm new in the forum, my name is Ariel.
I do not know if they have already touched the subject but I wake up with acceptable levels of sugar between 75-85 and I am in doubt of going down the dose or not during the day.
I have recently begun to monitor what I have dreamed of the sugar levels that were sometimes in 300 a.And now I am between 87 and 160, lower the insulin dose of 15 a of rapida to 10 a and 35 un.From slow to 20 a.But I would like you to guide me when I have normal levels.thank you

If you have good values, you have well regulated insulin.If you don't have hypoglycemia, don't lower it anymore.

The optimal glycemia values ​​are between 80 and 140 mg/dl between hours.With the values ​​you provide, I would not exchange the doses.
