I am new using insulin I started about two weeks ago. I am taking 20 units of Lantus at bedtime. I was wondering how long it took to find the right dosage? I have only had two fasting blood sugars that were under 200. I have been higher 200's when ever I test which I am sure is not a good thing. I guess the second question that I have do I need to ask about adding mealtime insulin or just the Lantus more time to work. I found out that I had diabetes November 13th 2012 and my A1c was 11.5. Thanks for any help.
