Have you used a CPAP machine? I have had severe obstructive sleep apnea for many years and once I started using the CPAP machine I have slept just fine with none of the symptoms I used to have like falling asleep at meetings during the day. I have heard the surgery does not always work well and there is always a risk with any surgery. The CPAP is non-invasive and, at least in the the US, it seems to be the treatment of choice.
