Wow. Thanks Shels. I can't believe how similar our experiences are. I've been struggling breathing through my nose so I wonder if the nasal passages are inflamed/blocked. the excess yawning is identical and the panic and anxiety are spot on. I get conscientious about my breathing and I get stuck not being able to complete the breath and then I become even more short of breath. My sleep doesn't appear to be affected either. Glad to hear you're seeing significant improvement. Hope it continues. Maybe I'll stop drinking coffee and beer and see how that affects my breathing.
