A sharp decrease in insulin demand for me lately

3. That is worrying.

I am type 2 using Lantus and have reduce that from 85 units once a day to a total of 42 units split in 2 daily. I know the reasons which are retirement which has reduced stress, regular aerobic exercise and carefully limiting carbohydrate intake. This has also been accompanied by 30 pounds melting away. That alone has probably increase insulin sensitivity.

I realize that 1 and 2 are different but both respond to various changes in life. I would certainly check with your doc about these changes. I hope that it is for good reasons. That alone will help your pocketbook as insulin is pricy and getting more so.
