There are a number of ways of treating sleep apnea :
1) Loose weight especially if your BMI>30
2) Sleep on your side if the apneas occur mostly on your back - for this you will need the doctor to explain the sleep report in a bit more detail ie spending 5 minutes rather than 5 seconds (by just telling you your AHI)
3) CPAP which is currently the best option as far as medical science is concerned
4) Surgery if your surgeon knows how to locate the exact site of blockage when you sleep by doing a sleep endoscopy and also is an experienced surgeon in sleep surgery
5) MAD (mandibular advancement devices) or TAD (tongue advancement devices) - not so popular, not so comfortable and effective

Please be aware that by not treating your sleep apnea, you are at a health risk - it is just like having diabetes and not treating it. Yo must never stop unless you have loss a lot of weight and another sleep study shows that your sleep apnea has resolved due to your tremendous weight loss.

Cheaper to buy from USA as the prices in Malaysia are about 30% more and they claim ti's due to their after sales service and two year warranty
AutoCPAP is the best and easiest to use as well as more comfortable but make sure the mask is one which you are comfortable with
