I'll put it this way, once insomnia really takes hold and you're beyond desperate to sleep, you try literally every RX, OTC med, and supplement you can take. Then when that doesn't help, you resort to trying things that you know won't work, but you try anyway, like tea's, not using the phone after bedtime, meditation, sleep apps, etc. When all that fails, you just accept that this is how it is, because by this point, you've spent thousands to try to fix it but have no positive results to show for it.
The messed up thing is the only thing that seems to work is Oxycodone. After my last 2 surgeries I slept great afterward until the pills ran out, so I had a definitive timeline where I know something worked. Obviously I can't be taking this every day to sleep though, so that sucks. I have no clue what else I could do at this point.
