Tinnitus - Cant sleep. Last 10 months,

I don't know what's my root cause. ENT said there is a possible blockage of in-ear tube. When I read why it happens it's like I have done all of them. 1. I have used earphones everyday for long hours in the last 10 months, thanks to WFH. 2. I have been smoking. 3. I have sleep apnea for a long time. 4. I have taken zolpidem that can cause it. 5. I clinched my jaw the night it started as per a technique suggested by doctor to help relax and sleep. 6. I was stressed and struggled with anxiety. 7. It's cold where I stay and I can't tolerate cold weather. 8. I sleep in a wrong position - on my belly. All 8 can cause T. I don't know what caused mine. Taking gingko biloba + vitb12. But its horrible at night. I just cant sleep. It feels so loud in the head, music not masking it. Ears and jaws pain when I lie down. What do i do to sleep at night? Should i try ayurvedic sleep inducers?
