First Night CPAP- Suffocating- Help!

I'm a Back and Side sleeper and have had very good success with the Airfit F30, Amara View, and Dreamwear Full, all full face masks. Airfit F30 is my new fav and is far outdistancing my previous fav the Amara View, and the Dreamwear is just ok...it's doable, not great but you can side sleep with. None of these are the large full frame type with the bar that goes up to the forehead, I doubt I'll ever try one of those, they look hideous to wear. I continue to rotate though all 3 but F30 definitely rules majority of the time.
