Sleep Apnea Support Group
Sleep apnea is a common sleep disorder characterized by brief interruptions of breathing during sleep. People with sleep apnea partially awaken as they struggle to breathe, but in the morning they may not be aware of sleep disturbances.
If your insurance allows, or if you can swing the costs, I would recommend a in lab study before buying anything. In my case, somehow the doctor's office managed to get both studies done and each billed as an office visit, so my copay was $30 for each test. Very good, and I suspect unusual costs.
Once you are sure that you need to proceed (and you are based on your post) the fun really begins; buying the machine. IMO, there seems to be a big scam going on at this point. Your doctor will refer you to their preferred DME, which will then sell you a machine that they want to sell you at often a very inflated price. The inflated pricing assumes that your insurance will be paying the biggest share of the costs, which may or may not be true depending on your insurance, deductible, and co-pay. In my case, I had to pay 100% because I had not met any of my deductible, but they (the DME) said that they would make be a deal and only charge me one-half the price of what they would charge the insurance company. Sounded great, but it was still double the price that I would have paid elsewhere.
Many times when you take into consideration your costs with deductibles, or high copays, it may be in your best situation to buy your equipment from a good online supplier such as my favorite cpap.com. If I had know of this before being stuck with a poor machine, I would have never bought the machine from the DME.
About six months later, I did replace my poor quality machine with a top-of-the-line model and now use my old machine for backup only.
This board and DS as a whole is very slow. I recommend that you repost your post on one or both of the SA only board at the links below. You will get many, many more responses I promise. Good luck!

I felt that CPAP seemed a little scammy at first due to the seeming indifference the docs had to the long wait times I had to deal with between appointments etc. This after their telling me about the "severity" of my apnea. I did my research though and their is validity to their concerns. It's just that in general, sleep apnea is not seen as an imminent threat to kill you before the next sunrise and so the seeming whatever attitude of the medical staff is learned over time I surmise. At any rate I would not be surprised if you could eliminate SA by side sleeping as your back sleeping AHI is borderline. Good luck.
