I was taking 100 units of Lantus at 9PM every night, it worked fine taking this dose for 1 & 1/2 years. Then I started to sleep for 15 hours on some days. My doctor told me to try taking 50 units when I woke up and the other 50 units at bedtime. My Mom has had to call the medic several times last month becauce I didn't respond to her call, so she called the medic, their meter just read "low" so the medics started IV's with dextrose. Taking Lantus this way isn't going to work. I am scared to take 100 units at 9PM and split dosing scares me. I need a long acting insulin. I don't have a doctor appt. until June 25, so for now I am just taking 50 units of at Lantus 11AM. My fasting blood glucose is too high while taking this dose of Lantus. What other types of insulin can I take? I take Novolog with meals, no problems with Novolog.
