I got a septoplasty recently (less than a month ago, still recovering from surgery) and I can 100% see the difference in my sleep quality.

My non-24 schedule is much closer to normal now. I no longer wake up with a completely dry tongue / nasty taste in my mouth.

Additionally my surgeon found and got rid of polyps in my nose which were the cause of my anosmia. I can finally sense smells again.

If you're interested in the surgery, contact an ENT for a diagnosis and a pneumologist for a sleep study.
