Quitting the CPAP--when and how?

Is the only way to stop using the CPAP to do a new sleep study and confirm you don't need it?

I swear, my CPAP has been making it harder to sleep instead of easier.  At 171 pounds, I'm way below the weight I was at when I started using it.  The company that fitted me into it calls periodically to check on me, and to send replacement stuff if I need it.  When she heard how much weight I'd lost she said that a replacement mask wouldn't work unless I go refitted, that the old mask probably isn't fitting at all, which would explain my issues during the night.

But honestly, I've been wondering if I even need it.  I slept the past two nights without it.  I'm not waking my husband up (the reason I first got tested--HE'S the one *****cognized the danger and googled the symptoms and told me to go to the doc and get tested) and last night I slept with my fitbit and it confirmed that I slept well.  (Which I knew--lots of dreams/REM sleep.)

I know I need to call the doc and sort things out, but I'm hoping I don't have to actually do another study.  The woman on the phone mentioned doing a new study so the doc could adjust my air flow.  She said my air flow was probably way too high for my current weight and that some docs would write a new prescription based on how much weight I'd lost, but others would have me repeat the second part of the study.

When I told her that I might need to repeat the first part, because I wasn't even certain I have sleep apnea any more, she said, "You've been diagnosed with sleep apnea. There's no reason to come two nights."

I dropped it.  And I'll get an appt with my doc, but I'm feeling like it's all a big waste of time and effort at this point.

Opinions?  Experience?  Anybody?

I was bad. I was diagnosed with sleep apnea pre-op and only wore my mas****il surgery. Literally refused in the hospital the very first night. Figured what were they going to do, put my stomach back in? That said, my apnea was pretty borderline ot begin with.

A new sleep study is probably a good choice before you bother with an adjustment. Sleep apnea can be caused by obesity and cured by losing weight. Obesity isn't the cause in everyone, and losing weight doesn't cure it for everyone but the percentages are high.

I assumed the weight was the thing, so it would automatically get healed.  Thanks for clarifying that.

 I had surgery 2.5wks ago and have already quit using mine. My husband says I don't snore and I feel very rested when waking. I have only lost 25# but can tell a huge difference. I think the only way to get confirmation would be to repeat the sleep study but if you are feeling good on your own then use your own judgement. Was snoring your only issue?

No, I would stop breathing and scare my husband to death. Plus exhaustion!  I've decided I probably need another study.  Thanks for the feedback.

I am on cpap. Do you have an auto cpap? Do you review your data on your computer using software? If so, you could do your own sleep study because you would see your apnea/hypopnea events minute by minute.

I don't guess I have that kind.  I can't review anything.

 I had surgery on 11/23/11.  I stopped wearing it on 1/13/12 when I drove to California.  At that time I think I was down 50lbs.  I knew I didn't need it anymore because I wasn't waking up with headaches anymore.  My friend told me I made no noise when I slept.  No mouth snoring/breathing.  I haven't worn it since.  YAY!  I wore that thing for 3 years straight.  

That's great news.  Congrats!

There are many skinny people with SA

The only real way to find out is to take a new study.  Your pressure may need to be lowered or adjusted.

To just quit is foolish, but its your health do what you wish.

I use  one, have lost 66 lbs in 3 months and was told by my doc to wait a year and go for a new

study.  I still wear it every night.
