While I can’t offer any advice on the Tresiba aspect of this (as I’ve never used it), I can offer a suggestion to help you make sure this never happens again!
I occasionally had “remembery” problems with Lantus - “Did I take it today?!?!”
I fixed it with this:
Don’t want to have a syringe pre-loaded for a whole week? Just fill it with empty syringes at the beginning of the week, and always use that day’s syringe to load your Tresiba everyday and inject.
Use a Tresiba pen instead of syringes? That’s ok, just put the pen needles in the reminder container instead of a syringe. Always take the pen needle out of the reminder, and you’ll always know.
