I did a number of years ago. It was an overnight observation, hooked up to all sorts of monitors. My wife had been concerned that I seemingly stopped breathing at night and wanted me to go.

I don’t remember my specific numbers, but they said it was very likely I had sleep apnea. I could go back for a second overnight and more observation to be conclusive OR (as my doctor put it) I could “become less fat”.

I really didn’t want to sleep with a CPAP machine if I could avoid it, so I went to a hypnotist and lost 60lbs. Over two years. This cured my sleep apnea.

Last year about this time, they found “mild” sleep apnea which is not life threatening but can contribute to poor health. My O2 did dip a little but I don’t remember how much. I have been using a CPAP religiously every night since getting one. Without it I immediately snore, with a CPAP I don’t at all. I felt improvement in days. I’m not very overweight and they said losing weight “may” help but it was more about the shape and size of my neck.

Yes. I use a CPAP machine. I never really had symptoms during the day but I’m a loud snorer. The CPAP has eliminated the snoring.

Result was: I needed a CPAP.

I don’t remember how many times I woke up, but it was a lot.

After starting to use the CPAP, it took a week or two to get used to the facemask. I learned that I don’t like the full face or even the nose coverings, but that the nasal pillows (that blow right into the nostril) were easy to get used to.

Once I figured that out, I slept and felt better in a matter of days. Really.

My husband has a sleep disorder and an overlong uvula. Mom had a CPAP when she was overweight but not anymore.

Yes. I was pretty sure it wasn’t going to be apnea, but I gave it a try.

I felt very lucky that the doctor who review my sleep called me personally. I asked him to allow me to guess one thing, which he did, I told him I felt I had longer deep sleep like a child, and he was shocked I knew that.

He told me I also have a certain type of brain wave that intrudes my sleep. I wish I could remember which one. If the search function worked on fluther I could find an old answer of mine. He said that found in people with muscle trouble and they aren’t sure if there is actually a relationship. I do have muscle trouble. I found that interesting.

The sleep study I did, if you show signs of apnea they wake you and let you try the breathing machine for another round of sleep. Some studies make you come back a second night! That’s a racket as far as I’m concerned.

I also about 6 hours when I was there, so probably 4 sleep cycles if I had to guess.

Edit: my feeling of low oxygen we relate to my slow heart rate at night. It’s better when I speed up my thyroid.

@elbanditoroso What’s the pillow? Does it allow you to get extra oxygen? I might want it. I love oxygen when I’m in the hospital. Lol.

@JLeslie look at this. The straps go around your head to hold the device on, but the pillows (that look like this) link direct airflow up your nostril.

Less noisy and more direct.

No. Every doctor wants you to go for sleep studies. I don’t need to and it irritates me. I have none of the symptoms. I also know I will never use one of those machines.
