Just diagnosed with severe sleep apnea. I stop breathing 40 times an hour and have no delta sleep.(anyone know what delta sleep is?) So to fix this I've been told I need a CPAP mask. I tried this contraption at the sleep laboratory and found it extremely uncomfortable. (looks similar to a scuba diving rig) Anyone have any advise on this CPAP thing? Do you get used to it? Does it really improve the quality of life with more energy & clearer thinking? Thanks for any advise.
