This is me. I met someone who once had a psychotic attack and told me she has weaned of to a micro-dose that helps calm her internal voice so she can fall asleep.
I convinced my doctor to try that medicine (after i underwent sleep trials) and it works really well. It's no sleeping pill, it just shuts up you internal monologue for long enough to get to sleep. It's great, it got me off my alcohol self medication. It doesn't make me feel sleepy, though, I need to remember to get to bed. But then it works.
Anyway the medicine is this one, of course check with your doctor, as I'm just a guy from the internet.
