Yeah looks very much like CPAP mask.
Can be totally unrelated to weight and health and just be that when you sleep your airwaves relax and constrict and you end up 'dying' in your sleep multiple times a night.
Takes years off your life, fudges up recovery etc. Loads of people have sleep apnea and never realise. If you're a snorer, have to keep waking up to pee, wake up with a dry mouth or feel like you're tired regardless of sleep it's worth getting checked out cause those CPAP machines are literally life savers.
Dealing with the NHS is another subject all together....
I keep on waking up to pee. Always thought it was the 10 pints of guiness i drank.
No wonder i feel a bit rough in the morning.
