hi. i am new to the forum. My husband has been type 2 diabetic for about ten years and it has never given him any problems. about four weeks ago his blood sugar levels were found to be in the 20s (highest being 29) He is now on 3,000 metformin and insulin injections. he is now on 60 units of humulin R but his reading just now before his evening meal was 20. Is it always so difficult to get under control once you start using insulin? He also has Crohns disease which I don't think is helping
