My heart goes out to you...it must be so difficult to watch this happening.
i guess the good news is that he must be soin something...or he would have collapsed in a heap already with dka.
I don't know what works with him...I had a few years of complete denial, and the more my Mum nagged, the more I refused to take charge of myself. I am paying for it now, as I have problems with my eyes.
Maybe you could try "joining him"? OK, so you can't do the injections...(and don't, it may kill you!) but how about a challenge...tyest your blood and carb count, deny yourself evrything he has to etc etc. i know it is never going to be the same, as being a none diabetic, your bg levels are always going to be good, but I wonder if this approach might help? (Don't let on to your GP, as they wouldn't be too pleased aboutthe test strips being wasted...so maybe just the finger pricking bit?)
Siunds daft, and laos like you are treating him like a child, but it might work. I am always better at going on a weight loss diet if I have someone to do it with.
The other thing I wonder about is how old he is? Lack of control will have fertilty repercussions, would this be teh carrot he needs to work on his control?
For me, it was a serious health scare...but it still had to be me who made the decision.
Ellens post is a very moving reminder of why staying on teh diabetic wagon is so important
Good luck!
