First off to have 2 weetabix pre bed without a bolus is quite a lot especially as you are effectively only raising a little without having any bolus...
So this would indicate that you would go low without it.
You have choices here:
Blood test every hour: or
Get a Libre....
With Tresiba you are likely to be flat until about 4am if you have DP... but it could mean that your body sinks and then surges up... so you need to find out.
Sorry, no other way but to test....or scan every hour...
Analyse those reaults and see if weetabix is needed.
Blimey, I would hate to have that routine of having to eat...
I reckon you will be going up anywhere from 4am onward...could be as late as 7am when rises start.
It really shouldnt be necessary to eat before bed without a bolus wvery night.
The idea of mdi is to give the patient some flexibility!! Not fix them in a routine of having to eat before bed every night of their life!!
(I do have to wake at 4.30am to do a correction bolus... so actually Mdi is not nice to me and I do have to have a blooming horrible routine each day!! Lol!!
