A whole new dumb mistake!

I inject Lantus as 75% of my basal, and use a Novorapid pen with a needle not infrequently. I’ve had a couple of cannula issues recently, with bleeding and ceasing to work after I’ve landed too heavily at martial arts. The last thing I can be bothered with when I’m high is starting a new cannula, so like a lot of people, I inject quick acting, rest and hydrate for about 20 mins, then get a new cannula started.
If I’m running low on a reservoir and out to dinner, I would totally inject Novorapid. Hopefully not through a sensor though. That is special! Though my sensors are in the back of my arms (Libre), so not too likely.
