Split dosing - is this "normal"?

Hi all

After 20 years on the same regime (Novorapid X 3 bolus) and 1 X Insulatard overnight, I switched about a year ago to split doses 2X Insulatard 12 hours apart. The advice at the time was to split my old 20 units Inulatard dose by 2 ie 10 units twice a day.

After fiddling around with it for a while I had landed on 13 overnight (10pm) and 8 day time (10am) with Novorapid X 3 for food.

I've just got a Freestyle Libre and its highlighting that I think the 8 may still be too much.

This seems odd. Is such a split (much more required overnight than in the daytime) normal?

Many thanks
Karen

Ps Novorapid is pretty low at 4 units breakfast, 2 lunch, 7 teatime. I am a pretty avid exerciser and observe my own version of moderate carb consumption. Three years ago I was on 80 units/ day and weighed a lot more, so this feels low to me but it may not to others! T1 for 38 years.

I think it's the proportion of the split, rather than the split itself, that @KarenG is asking about? I.e is it normal to take 38% am and 62% pm

I think you don't need to worry so much about what is "normal"* if your libre shows your basal is working for you, that's the main thing. Dont get too hung up on what is normal/average - they are good starting points - the important thing is what works for you

Edit: *normal for the proportions of the split. I think they usually split the basal 50/50 am/pm when people start off splitting it, and then fiddle about with it as you have done to figure out what works for the individual.

Tim, thanks for your help but catapillar understood what I meant - the (obviously not clear enough!) question was about the proportions and not the split itself. I feel like I should defend the diabetes team by saying that I never proactively asked for dosage/insulin help until a year ago and they then suggested splitting the dose. Ironically I only really sought their help after getting advice here. the Insulatard was never meant to be 24 hour cover, it was simply for overnight, and I realise was a very old regime.

Catapillar - thank you very much - I will stop fretting and keep fiddling

Thanks Martin. I am surprised, I guess, that the Dawn Phenomen would have such a material effect!!
