Hi . That must be super frustrating. Have you had any further testing done to determine whether there is more than sleep apnea impacting your energy levels? My husband was still sleepy all the time after he started on his CPAP. Turned out that he was super low on vitamin D. His body simply doesn't produce enough. Supplements made a big difference. There are so many other nutriential deficiencies that can impact energy levels along with some hormonal disorders. They are all easy to test for as well. My heart goes out to you. - Lori (Team Member)
