I've been given one for a 1 week trial to see if it will help my constant fatigue and hungover feeling. One of two home studies scored highly likely for mild sleep apnea, the second one came back normal but the consultant suspects an upper respiratory disorder or something like that.
The problem is I keep waking up after 2 hours and can't sleep with it on again. A week long trial isn't enough to get used to it either by the sounds of things.
How did you find it at first and how do you find it now?
