When I was first diagnosed I was needle phobic, couldn't stand being in the same room. To begin with I had district nurses come twice a day and inject a mixed insulin. Later on the doctor offered me a set up where I never had to see the needle go near my skin. It was a clunky piece of apparatus, driven by air pressure from a canister. You basically rested a plastic circle against your skin, pressed the trigger, and it went bang, inserted the needle and injected all in one. He demonstrated it for me, and I was out the door at the bang. I didn't think they could make injecting more terrifying. This was nearly 20 years ago, so I don't know if the device is still available.
