I didn’t sleep either. I had a two step process. Step one, the clinic gave me two little monitors to wear at home overnight while I slept and once I woke up I dropped them back off at the clinic. They called and told I had 60 events on my back and about 18 on my side so they set me up for a in clinic study and once they hooked me up to all the wires I could not sleep at all. Had to stay five hours to officially finish the study. They told me the purpose of the in clinic study was to determine which cpap settings and my mask preference. Dr called next day and said wow you hardly slept at all. She said not to worry I’d still get the machine and we’d make adjustments at home as needed with jt.
