I weigh about 425 lbs (Almost as much as Chris Christy}
Back in 2006, my doctor suspected that a guy my age, and being "circus fat", I might have sleep apnea, so he sent me for a test. I suspected he was right because my wife said I would stop breathing in my sleep
I used to get up to pee about 4 times per night, and I would always wake up with a headache, even if I had not been drinking
I have since used my CPAP every night. No more headaches. No more getting up to pee
It took a little while to get used to, but when I would take it off while sleeping, my snoring would wake my wife, and she would "throw me a 'bow" and I would put it back on
I never go without it now, and I even take it out of town
