I have, I've tried LANTUS and LEVIMER over the past few years, Both had several peaks during day and nightcausing low blood sugars, but at least the peaks always occured at the same time. 15 mnths ago I started treatment on a basal insulin called TRESIBA, It worked well for the first 2 mnth's, then suddenly started becoming unstable, peaks were varying and HYPER in the morning. Now it's even worse, often 4 lows a day and always 20 mmol/l after breakfast for the first 4 hrs. My hospital diabetic docter is set in his ways and thinks TRESIBA is a miracle cure. I think I need a more stable basal rate, like an insulin pump, what do you think, any ideas about how I can get one, when you have a diabetic docter who doesn't like insulin pumps ?
