That's a long time!
I took myself of medication because I could see it was just a way to sweep the issue under the rug, whilst letting it get worse. I had the added issue of nocturia, so I actually had to not sleep or risk urinary retention.
What's happened recently, is that doctors and especially psychs have left me alone so I don't feel as threatened. I've been trying to listen to my body and letting it control what I do. I've been managing to sleep more despite my nocturia, but still getting up when my body tells me to, because I'm not sedated by any medication.
I've also been taking CBD oil, which may be a placebo, bit it has coincided with better sleep, so I'll take it.
It's a very fine balance for me: listening to my body, allowing myself to sleep but retaining enough awareness to wake when I need to.
Ironically, this is a skill I learned from camping alone in remote places without a tent. I'd sleep cuz my body was tired, grow accustomed to what were natural non threatening sounds, but wake if there were any sounds that didn't fit. So a fine balance between managing need and threat response, that can only be learned by being aware of your physical needs in balance with your mental needs.
Sorry, my answer isn't a quick one, as it's a difficult issue and one I still struggle with sometimes.
But I'd stress that medical sedation only upsets your natural equilibrium, even if it helps in the short term. Learned that the hard way.
