Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: HANK YOU SO MUCH! What you said, I think you may have figured it out. Last year, I started grinding my teeth at night. I would wake up in the middle of the night because I would slam my teeth together, and started to develop TMJ pain. So, I had a custom night guard made, but then I found I would it would keep my lips slightly parted while I slept, which dried my mouth and throat while I slept. So, I bought a velcro anti-snoring head strap (https://www.amazon.com/gp/product/B081NJT3YF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 but an older model) but in order for it to keep my mouth shut, I had to get it pretty snug, which I now think may have been pressing on my airway.The last week or so, I've been only attaching it partially (the part on the front part of my jaw, and wearing a sleep mask to keep out light, which helps keep it from riding forward/backward and falling off my head, and I haven't had any significant episodes since. A little chest pain here and there, and a sensitivity to any form of anxiety or overstimulation (I think my body might just be in a very hypersensitive healing state right now to encourage rest, I was only getting about 4 hours of sleep during those episodes, and waking up several times a night).I am waiting on old ECG's from 10+ years ago, so if it shows the taller P-Waves, I guess it might just normal for me, probably precipitated by the head- strap airway obstruction. I've always had chemical sensitivities that manifest as chest-tightness/shortness of breath. I've had many doctors since childhood tell me that I might be considered borderline asthmatic, but I am a minimalist when it comes to pharmaceutical interventions unless I cannot get around it with diet/exercise/lifestyle changes.I will still go ahead with my doctors appointments for due diligence, but I think you have solved it and helped ease my anxiety enormously. Thank you again! : ). ### Response: That is very interesting! But yes that was interesting when you said you were sleeping better now. Demonstrating that you can tell when something is better. I would not worry about the old ECGs, I would not have really called that R Atrial Enlargement, it is mostly normal.Happy to help!.
