You may just have what's called positional apnea, and if you can stay off your back (there are long foam wedges designed to help with it) you may not need anything more. Here's a thread by a previous member. I have edited non-relevant bits out for brevity.
Hi Everybody
As most of you know, I have been experimenting with myself, and using positional sleep apnea therapy for my obstructive sleep apnea (untreated AHi = 41) for some months now. The recent study I posted on positional sleep apnea is worth noting - in particular their conclusion -
"Positional therapy has the potential to be an effective therapy in a significant proportion of patients with sleep apnea. Rigorous outcome studies evaluating the efficacy of this treatment modality are urgently needed in patients with mild-to-moderate sleep apnea.
According to the experts at the American College of Chest Physicians in an October 2005 issue of "Chest" magazine, as many as 60% of the people with obstructive sleep apnea experience a lowering of symptoms when they slept on their side as opposed to their back. They estimate that as many as 50% of the people that experience sleep apnea could be successfully treated by using positional therapy."
I knew from my recliner/napping times with an oximeter that I did not desaturate with my body nearly upright, and my head back; and that I did desaturate if my head was forward, or my body more supine.
I also remembered seeing some Forum posts of the head being moved backwards, so opening the throat. This being cited as a possible help in overcoming obstructive sleep apnea. So I bought my first soft cervical collar for $8 from the medical equipment shop, and tried it out.
And that was when my experimenting became testing, as using the collar and sleeping on my side meant no desaturations.
The starting point is sleeping on my side - all night. I have also worn an oximeter every night since I started this, and the only time the alarm went off is when I have deliberately turned onto my back and fallen asleep again. I no longer do this.

and I still use this most of the time - but possibly no longer need to -
and, of course, the soft cervical collar - together with a feather pillow -
I no longer use a cervical collar, but advise all those experimenting to start by using one. When using the soft cervical collar I do not use the cervical neck support pillow, I use a feather pillow. I now use a cervical neck support pillow which keeps my head upright, ( head in the dip and chin resting against the edge,) and serves the same purpose as the soft cervical collar. The pillow has less resistance than the collar, so I believe it is best to use the collar first until one is used to the head being upright in relation to your body when going to sleep.
I am still experimenting with the two inserts, but it works with and without the inserts. I also have two oximeters - CMS50E and CMC60D.
I have just had another full diagnostic sleep study, using only a cervical collar and thigh wedge support and back wedge and the doctor has told me that I no longer need to use the cpap machine.
So there it is. The prescription of cpap machine is easy, it works if successfully applied, and a whole manufacturing and retail industry is supported by it. And I have no argument with that. But for those it does not suit - for whatever reason - taking the steps to find out if positional therapy is for them - may be a step well worth taking."
