I'm a Type 2 not on insulin, hopefully someone will be check in and offer you an experienced response. But in the meantime, I've heard high recommendations for these 3 books to help with insulin questions. Maybe you can find them in your local library. One of them I know you can read parts of it on line.
Using Insulin by John Walsh. He also has a book called Pumping Insulin.
Think Like a Pancreas by Gary Scheiner
Diabetes Solution by Dr. Richard Bernstein. Can read some of his book on line here. At one time, the part about splitting the dose of basal (long acting) insulin into two doses was on line.
Hope this is of some help.
