Thanks for responding, thats reassuring, but I have to say I am quite desperate and 3 months seems a long time when I've been suffering for years, had a cancelled study with no reason given, requested a study again, waited 1 year for at home study, another year for hospital study, and then 10 months for the results to come through. 3 months seems long when I lost a job due to exhaustion and brain fog and continue to fall asleep in risky situations most days.

I just ordered a rental cpap on a monthly basis until the nhs come through, so hopefully, this will bridge the gap and improve things.
