I agree that you need to look at reducing your basal as you are likely to be more insulin sensitive at the moment.
I can't remember what you chnaged about your basal after your clinic appointment, did you split it or chnage the timing?
Do you get up every night to go to the toilet?
Just wondering if you could be going low every night but only picking up on it when you get up to the toilet because you test them. Not because you wake up with symptoms.
