Hi, I have recently been diagnosed with severe sleep apnea and I'm due for my CPAP machine in just over three weeks. Obviously new to the whole thing and will probably have loads and loads of questions coming ths way but....I was wondering if any of you guys in the UK could tell me if you get the choice in what mask you get? I'm a genuine mouth breather and I don't know if they take this into account? And.......How successful is the treatment against snoring?
