18mol/L

Hi
I have checked my blood sugars and cannot get them below 15mol/L it's been like this for a week.
Today it is 18mol/L. I have lost weight and have a dry mouth and drink a lot of water and urinate a lot.
I am on Metmorfin and Glickizade 4 or each daily.

I suppose i need to go on to insulin ?

Any advise

Thank you Tracey will get an appointment and get checked out
