No, you should not be on short acting insulin yet. Your doctor should let you remain on glyburide while taking long acting, once a day, Lantus. I am on Glimperide and Metformin, but I am taking once a day 129 units of Lantus insulin a day. My doctor had me increase 2 units of insulin, once a day, until my blood sugars were 120 on my morning fasting blood sugars. I tried going off of my pills and into short acting insulin, and I felt sick and my blood sugars went up. My Doctor kept me on my pills. However if I ever had to start short acting insulin, he said that is the time to take a patient off of the Diabetic pills. I get sick without my pills with headache, and sick feeling. So for me, being on pills and taking long acting insulin once a day, and eating low carbs, that is how I keep my blood sugars down. Eating a low carb paleo diet of not eating any grains, helps me stay in normal. You have to test yourself a lot, before meals and after meals. Keep a journal what you eat. If your blood sugars on high from the foods you eat, then you learn what foods you can or cannot eat. Eating meats, cheese, eggs, fish, chicken, these are all zero carbs. And vegetables is the healthiest way to eat for a Diabetic. We don't process the same as a non diabetic person. I know two guys who were on 4 insulin shots a day, one long acting and three short acting insulin, and when they went on the paleo diet, Mark Sisson's Paleo Diet, their blood sugars went to normal, lost all their weight, and are totally off of insulin and any Diabetic medications. Paleo Diet maintains normal blood sugars. When they went off the Paleo diet, their blood sugars zoomed back up to full blown Diabetes. So they control their diabetes now by diet only. I'm starting this diet. And yes I know these people personally. It really works. Just thought I would share these choices with you.
I have been on Lantus AND Humalog for 6 years now. You NEED a fast-acting insulin. If your doctor continues to refuse to work with you - change doctors. I had an idiot that seemed to be afraid of insulin. He dropped my Lantus from 80 units per day to 2, and my Humalog from 35 units 3 times a day to 15 units once a day. Then he had the nerve to wonder why I was letting my sugars be so high!
It's your life. It's your body. It's your disease. The doctor is PART of your health care team. Does he need to be off the team?
