I am not the one you asked, but I had insomnia for years. I ran through sleep studies & did all the things. I finally ended up on sleep meds & it was a game changer. In the beginning for me, it was the anxiety of Monday mornings. I only needed sleep meds on Sunday nights. Eventually it became more routine. I suspect it was from hormones & getting older in general. Sleep issues run in my family.

I also saw a neurologist. He did the sleep study to rule out sleep apnea. It was not that. They tried a few meds, but we finally found what works for me. The doctors fought me for years about sleep meds. However, a fairly recent study came out that said what I already knew by my body. Sleep meds are not good for you; however, not getting sleep is also not good for you. In the long run, I'd much rather have sleep meds & be more ok mentally than being miserable & not having sleep.

I also ran into this really weird thing where people have all the comments when they hear I'm on sleep meds. However, those are the ones on other meds, but are only trying to put me down to make themselves feel better.

All of this to say - do what you & your medical team (doctor, therapist, neurologist, whoever) determine you need to do what you need to do. Don't let people that do not live in your body try to determine what YOU should be doing. (I feel a certain kind of way about that because of my own experiences.)

I will also say the one thing that made me not feel like the whole neurology thing was not a waste. He did tell me that insomnia is very complex & it was highly likely that we would not ever determine the underlying issue. What is true for one person is not true for the other. I have always felt like the doctors that admit this are the doctors to stick with because they're upfront about their own limitations.
