Couple of quick n dirty inputs:
 

re..How do you know if you have sleep apnea?
Many symptoms listed with a quick google search. To confirm---You can get a "recording pulse oximeter" for 50-150 bucks. It will record your oxygen level as you sleep. Try it for a couple nights and see if you notice a "sawtooth wave" where your oxygen level ramps down over a 30-45 second period and then jumps rapidly upward when you finally gasp for a breath. IF you have an issue, you'll be convinced of it (and the magnitude) before you stick your toe in the water with your doc and the FAA.

re..carrying distilled water.
My brother has been using CPAP for over 15 years. He uses tap water. Think about it. Tap water is distilled water with some extra minerals in it (unless you're in Flint, Michigan or something). In the morning, you have a slightly higher concentration of minerals in the water that's left in your machine. Dump that out, rinse it and use new water the next night. Or, drag around bottles of water and explain whazzup with that to every TSA guy you encounter. As previously mentioned, you can clean it out much easier than you can carry the bottles of water.

re..Z2 noise/roughness. Recommend turning their pressure relief feature to the lowest value. Lose the inline muffler thing that comes with it, saving some packing space as well. Put machine below the level of the bed behind a (noise absorbing) pillow. Go to amazon and get a "travelhose" collapsible CPAP hose, makes it much quieter.

Hope some of that helps.

Cool. Thanks!

Adding to CCNs info.....I struggled with a diagnosis of sleep apnea for some time. Was initially told is was OSA....obstructive type. Didnt adapt well to cpap machine and just used an O2 concentrator at home for awhile. Found out thru personal research about "central" apnea. After 2 sleep studies it was determined central was my problem. Prescribed a different machine and now have consistent O2 levels and no breathing stoppage. Before it was at "severe" levels.

BS. Your BMI is 25.5. Lose 5# and you are a healthy weight. Morbidly obese (BMI>40) would be 335#. Not saying you are BSing, but someone is, and as you get tall BMI becomes too restrictive.

The Navy flagged me as Obese due to weight vs height in my medical record. That's the VA stance on why I'm "obese".

BMI is the most retarded health measurement ever conceived.

Isn't that a little politically incorrect? :D I can't resist anything that has a "Mongo" in it.

So, what is a better way?

Total body fat seems increasingly easy to measure.

Calipers work. There are scales that do a fairly decent job. Delta used to do a dunk tank that would cycle around the bases. MRI the fancy way to look for fat tucked in around the organs.

Honestly though? A quick look at 99% of people with their shirt off while on a scale tells the tale. It ain’t rocket science.

Yeah, have to agree. seems most of the people that don't agree with BMI can't see their toes tho.
