Hi Douglas ;

Something seems very wrong from the beginning. I am no expert to say the least but I fail to see how your CO2 levels have not decreased, especially as you have managed to stay on it for so long a time.

I don't know if any of the drugs you are talking have affected the breathing muscles, I know that tamazipan and others affect mine after a few days.

Do try to get any settings and record them and make notes.

Good to hear that you have plenty of TV channels.

Love Terry
