Hello fellow type 1s. I have recently started Tresiba insulin on 4 units once a day which seems to be working well. I'm a slow diabetic was diagnosed August 2016, so still have my own insulin. Overnight my levels regularly drop in the 4s once I had a 3.7. I'm always worried if it goes into 4s I will go below and won't wake. Is this necessarily true? I've got into a bad habit of eating during the night when I get into 4s.on the other hand don't like eating as I eat too much and it raises blood sugar. I wake up with good sugars 5/6/7. But sometimes I wake up with almighty headaches and feel very week when I wake if I slept through the night.
