Phone your team and ask them how to manage a further reduction in insulin so you stop getting the lows....?
Being permanently hypo is no way to spend your day and strongly suggests to me that you are having too much insulin. Let me assure you that it is not normal for diabetics on a correct insulin dose to be getting hypos all the time (or at least not in any of the three countries I've lived in. or the 52 years I've been taking insulin.)
Do you have access to a continuous glucose monitor (eg freestyle libre or dexcom)? That would at least alert you when you bgs start to go low (day or night). Are you doing a blood test before you drive to breakfast or when you get to breakfast. Getting behind the wheel and potentially hypoing is very very dangerous and you are right to be scared of these hypos.
As regards the food, I'm at a bit of a loss, because most of the new diabetics I've heard from have their insulin gradually increased from a lower level until their bg levels come down, rather than the other way round. They carry glucose as an occasional hypo cure, not as something they have to consume 24/7.
How high are your levels going after dinner? To be honest, I wouldn't worry too much about temporary highs while your issue is the lows. In the long term, highs are damaging, but hopefully in the medium to short term you will get your insulin adjusted so that you aren't permanently hypo.
Normal hypos (ones that aren't happening every day) are conventionally addressed by fast acting carbs (glucose is the fasting form of these) plus something a little slower acting to pull up your levels in the medium term. So your night time regime sounds good to me, though it were be better if your insulin could be adjusted so you don't get night time hypos.
Lots of virtual hugs. Things will get better once you are on the right medication.
