wow you beat me by 9 years, respectI have been type 1 since 1959 and I too remember glass syringes, metal needles, urine testing by test tubes and clinitest tablets, I also remember an autoinjector which was just like a gun onto which you mounted your syringe. I think insulin pens are great but no one has ever mentioned I have a pump. I have had heart surgery but I still play tennis twice a week and go to the gym. I still stick to the carb counting I was taught originally in 1959. My Hba1c readings have been variable over the years but the last one was 51 in new terms.
Now you mention it, I had one of those autoinjectors. It was savage, really nasty, makes me cringe thinking of it now.
i have wondered about a pump, but I did use a Dexcom CGM for several months, and I found it uncomfortable in the end, and I've been told that if I didn't like that then I might not like a pump
Hba1c of 5.1 is impressive. I think my last one was 6.1, maybe 6.5, something like that (got the paperwork somewhere).
