Hello I have had type 1 for 44 years and even though I know a lot about Type 1 I am always learning more so need some advice at the moment I have just had a triple heart by pass 3 weeks ago and I am starting to have low blood sugars during the night even though I ensure as I have always done my levels are adequate before going to bed, I have reduced my base insulin which has seen no difference, please advise, many thanks
