Thank you for contacting CPAPSupplyUSA.COM
It is fortunate that you are on a lower pressure, but I would strongly recommend you invest in the purchase of CPAP. Untreated sleep apnea can lead to so many health problems such as heart disease, hypertension and diabetes, even a mild sleep apnea. The wearing of a CPAP can help also wtih the symptoms you have described.
You may not need a CPAP with all the extra features. I highly recommend a CPAP with a heated humidifier. Take a look at the Cardinal Health Puresom. This is a very reasonably priced, reliable CPAP.
Please contact us again if we can be of further help. If you purchase your CPAP from CPAP SUPPLY USA.COM, you will recieve on going support and education as needed. We look forward to meeting your CPAP needs.
