As you been a type 1 for almost 20 years and you are typing numbers above 20... You know this isn 't ok.
What help are you expecting? If you are type 1 for 18 years you should have a correction bolus ratio worked out and needing to do this...and realise how you are up in these higher levels and do something about it..
I suggest you go back to your consultant if you remain high and unable to establish better control.
