Any recommendations for my very particular sleep issue?
All my life (even as a little kid) I've had trouble falling asleep. Staying asleep has never been an issue, just the falling asleep part.
I've been taking doxylamine as it is the only thing that has actually worked in my life, but I want to stop using it because it's obviously very unhealthy to use long-term and I've built a tolerance for it where it doesn't make me feel tired anymore. It still "works" though, because I fall asleep on nights I have taken it, but when I haven't (like I just tried last night), it is literally impossible for my brain to switch from awake to asleep.
It's honestly scary at this point. The circumstances can be perfect, I can be completely relaxed, not worried about anything, body temperature perfect, in dead silence and darkness, on the edge of falling asleep. But then my brain just stays awake in that state forever and can not switch off. It's like the off-switch is missing completely.
I am planning to go to a store today to try something new, but I'm not sure what to try. Maybe glycine or GABA? Although when reading about it on Reddit, it seems that these are more for staying asleep rather than falling asleep. I need something that stimulates that missing off-switch in my brain. I think supplements that make you feel drowsy tend to work, because that's what doxylamine used to do to me and that worked like absolute magic back then.
Please, I really need some advice. I will also go to my doctor regarding this because it is obviously a very serious problem and taking doxylamine for the rest of my life is not an option.
