I exchanged my CPAP a couple weeks ago, due to questionable malfunctioning. I since have noted scare discrepancy (0.3) I feel so much better too! I conclude that surely something went 'haywire' with that other machine! although I still battle with fatigue, I have a much higher energy level-I have not needed daily naps. Thank you all for listening, support, and suggestions! Lantern4life
