I'm only about 5 weeks into my therapy, and just this week I've found the mask that suits me well (Swift FX), after being given a F&P Simplus Full Face initially, then a F&P Eson nasal mask, then tried a Respironics Comfort Fusion nasal mask (awful).
I've had the best sleep yet in the last few nights.
AHI has been under 3 for last few days (1.9 last night), my best yet.
So I'm pretty stoked with how things are going and this week has been a revelation.
I've felt the best I've felt in recent history.
But I'm wondering if the leaks I'm seeing in Sleepyhead are significant?

I haven't felt any leaks - the mask seems to fit really well, and aside from sore nostrils as they adjust to the nasal pillows, it's really comfortable.
I don't feel like I've been having mouth leaks - no dry mouth at all.
