I recall the time pens came out for Diabetics Type 1. I stopped them after a week or so and started using my syringes. I found that the pen was not giving me the required dose of insulin. It occurred quite a few times and my GP said, maybe it's just a poor batch of pens. That set alarm bells ringing for me. At least with syringes, you know exactly what you are getting Now, I see there are Pumps for insulin, I will not venture down that particular road either as I quite honestly don't trust the regime of administering insulin in this way. I have used insulin syringes for 31 years now and without any issues. Oh, and guess what, I haven't cried once whilst taking my jabs.
