I was diagnosed in 1971 glass syringes surgical spirit on injection sites you had to hammer the needle in . Clinitest urine tests to work out what your sugars were . The thought then was keep sugar high and never have a hypo which I didn't but I had lazer on my eyes , heart attack , heart triple bypass , vascular disease , toes amputated and lastly a below knee amputation . The morel of this tale is keep an eye on those sugars because there's a price to pay . Diabetes is one ***** of a disease .
