I think
@mick196572 you mentioned you are having regular conversations with your diabetes nurse.
I would recommend discussing your results and concerns with her before making any changes.
There may be some very good reasons why she is slowly bringing your BG down.
My 100% recommendation is to take
NO action based on advice from a helpful person on a forum who does not know you and your circumstances but to use the experience of people on the forum to structure questions and concerns to bring up with your nurse.
As you have just been diagnosed and in the honeymoon phase, I see little point in basal tests as your own insulin output may be unpredictable.
To be honest, I don't remember how long it took to get my levels down but I don't think I started as high so my experience is probably not relevant.
