My husband has been diabetic for 2 years,57 yrs old, thin and has been using levemir at bedtime and 500 mg metformin 2x a day,the past few weeks his bs no matter what time he checks it is consistantly 200-300 and basically eats the same every day and is active during the day and doesn't eat many carbs. I am type 1 and thinking he may need to split the levemir dose or increase the metformin as he has increased the levemir from 17 units to 21. He goes to his doctor in few weeks but thought I would see if anybody could suggest what he could do to lower his sugars.
