Sleep apnea can cause a chronic daytime cough. Eating and drinking can trigger it. Basically your throat gets roughed up/inflamed from all the snoring and airway inflammation.
On that - I started using the Intake nose tabs and they legitimately work wonders. Combined with a mouthpiece to correct jaw posture and force nasal breathing and overall I can notice a difference. I'm less sore in the morning and more energetic. With no other dietary/exercise changes my BP even fell a couple of points also. It's pretty stark when you see the medical impacts of nasal versus mouth breathing especially for sustained periods/at night.
If you have sleep apnea, the oral appliance is where you are getting your results. The nasal strips are voodoo.
I have super thin nasal passages, probably a deviated septum, and usually struggle to get enough air - it helps in that regard. The mouthpiece worked well but I still had mild headaches in the morning. Headaches were gone after the nasal tabs started. I'm usually pretty wary of placebos but feel pretty strong that both are needed together to work well.
You really need to get a sleep study. You also need to have a morning aligner made so that your teeth don’t shift from the mouthpiece.
I used an spo2 monitor overnight and the numbers were good - didn't do a formal sleep study but DR looked at numbers and judged not really worth a study once nasal tabs and mouthpiece showed more than adequate gains. Also, wife's a lot happier now so that clears the biggest hurdle.
That stuff raises your risk profile for damn near all the bad stuff. You should give it a real effort.
We got our azz kicked. Edit: No one needed a machine to help them breathe while they slept (in our section). I made my son stay. I had keys to truck.
