I have had issues with sleeping through the night for years. I have thought it was my sleep apnea, but getting evaluated and a CPAP machine did not help me sleep through. The first night with my new pillow I slept for almost 5 hours before waking up. Since then I've been averaging at least 3 to 4 hours of sleep before waking up at least once during the night and then still getting another 2 to 4 hours after that. I never would have thought that a pillow would be such a simple solution.
