I'm late in throwing in my 2 cents worth, but in my view the good benefits began right after starting therapy. In the first category of good benefits, I no longer had to fight from dozing off behind the wheel and I no longer awoke at night gasping for breath. Also, I no longer received spousal reports of struggling to breathe during sleep and loud snoring. In addition, my risk of all sorts of nasty health problems was reduced, since untreated apnea can lead to a number of serious health issues. To me, this first category of good benefits is paramount. The second category of good benefits is the feel good or better variety. This one is where almost every person has a different experience. I'd say, it took at least a couple months, as Sleepster mentioned, to truly feel better during the day. And this feel good variety can vary even from night to night, depending on things like nasal conjestion, number of needed potty trips and even my mental state that night.
A final note (if someone else hasn't already mentioned it), your reported AHI numbers have a way to go to reach what's considered effective therapy levels. This used to be an AHI under 5, but recently, some sources have switched to a goal of under 10 as reaching good therapy. I don't believe you will experience the best of the feel better category benefits until your AHI gets down into this range.
I only had 6 hours sleep last night, 3.5 on CPAP until my nostrils got a bit blocked and the rest was dozing without it. Today I felt like crap and know I should have bothered to get out of bed, used the nasal spray I've got and waited for it's affects to let me get back to sleep. A night without CPAP is now very obvious. I also removed the soft cervical collar and in hindsight that was also a mistake. I suppose the flight back from Perth, a late arrival at home and a two hour time shift all contributed. I'm going to bed after this post and the mask will stay on all night.
So while my figures are good but not brilliant at this point in time, the progrees I've made is very noticable when I don't use my machine.
I have been using my CPAP machine for 12 months now. It has made no difference to my tiredness. I only get to sleep for 3-4 hours per night but keep the mask on for around 7 hours ( I usually go to bed around 11pm and am awake by 3.30am).
When I look at my Sleepyhead software it shows me having sleep apneas even when I know I am awake. I am averaging about 6 AHI's (my test results were from 16 to 28)
It does stop my snoring, but I do wake up with a sore chest every morning.
Have stopped using machine for over a week and only difference is no sore chest. Still have very little sleep and still tired during day.
Specialist has no idea what the problem is, but said it would make no difference to my health if I did not use it as I am mild to moderate.
Anyone else have any similar experiences? Is the specialist correct about no long term effects if I do not use machine?
