Hey, so I thought I would try mouth taping. Without tape, AHI around 7 (up to 11) – with mouth taping, it drops to 2-3. At first I thought, hooray! Great numbers! But after a week I noticed huge rings under my eyes, and felt constantly exhausted, so went back to untaped sleep, and my general feeling improved again. Has anyone here an idea, why this might happen, or went through it also and solved the problem?
