When we inherited this house my husband and I found my dads diary. he kept incredicble records of every sugar and how he felt. Two weeks before he died he recorded more than 1 BG reading, he was in the high 240s on average.

When oral medications fail, usually within the 5 year mark, some quicker as mine at the thre eyar mark, doctors simply prescribe more of the medication. the problem is two and three fold.
becaus ethe medication stops working depression sets in as the pateint feels to loose ocntrtol, So basically is become Its not helping why should I continue to watch what I eat and do the things they say when its not helping.
An uinderstanding doctor, or a diabetologist understands that oral meds fail. changing meds also fail because they dont ontrol liek they should. So depression, frustration and anger hit hard.
An understanding doctor woudl explain that this happens and that it is nwo time to get back into control.
Usually they suggest one night in a hospital. A simple stay to see if the insulin shot will help. If it shows a dramatic change in sugar levels then it is suggested that a stay for a day or two longer to get insulin adjusted is needed.
When insulin is intrtoduced ther is a weight that seems to lift, a cloud that seems to pass and a new feeling of being " human" comes over you. I know I was there. I am still there.

With the new once a day shots its easy to be back in control.
But he has to be informed regardless. You could leave a paper with something about it for him to glance at, you can get acopy of any diabetes magazine including some free ones have the literature around. It helps......
