Well I have done it, changed the cannula and replaced the cartridge for the first time. I had a minor blip, but learnt from it. Hopefully Tuesday's change will be a little easier.
Testing in an hour to make sure I'm not through the roof.
Well done! I was so nervous about if I had done it right when I did mine My nurse recommended checking after 2 hours as depending on how long you find it takes for insulin to work it's way through your system you'll still have some left from the old set .
