Hey Barney 🙂
Hope brekkie worked out okay.
Just to touch on the initial should I still take insulin when at good numbers, I don't know if its been explained to you properly what your insulin does.
So mixed insulin has basically short acting (bolus) insulin in with longer acting (basal) in the same jab.
The short acting insulin is used to help deal with food and correct high blood glucose and the long acting is to deal with the glucose trickle that happens in your body throughout the day and gives your the basic energy to live.
Taking mixed means you can't really skip a dose without impacting the rest of the day (as you are not getting the longer acting cover).
If the mixed isn't suiting you and you want some more flexibility, asking for a separate short acting and long acting can provide that flexibility. Shouldn't be an issue to arrange that.
Downside, more jabs in a day.
Upside, can choose to reduce/increase each dose per meal as needed (with some guidance) and can be flexible with mealtimes or skip a meal entirely without leaving you without background cover.
Mixed works for some people with fixed meal patterns and routines. If it works for you, crack on but there are other options available to you if you wanted to go down that route 🙂
