I was treated for Type II diabetes for 12+ years, and the medics could never really understand why my long-term bloods were 'good' when most other indications weren't.
What I hadn't told them, of course, was the true amount of alcohol I was getting through, which in (British) medical terms made me a fully-qualified alcoholic. I was suffering from a form of 'sugar' abuse, but it came in a bottle.
And when I faced up to it, and stopped drinking back in 2002, I stopped 'being' a diabetic. And lost my left leg, as a direct result of the decades of drinking. And now suffer from retinopathy, and glaucoma, also as direct results of the drink.
Just something to ponder on, if you consider yourself an 'average' drinker, as I did!
