I have had frequent problems with sleep too. Due to trauma I have no memories up that come up when I'm about to sleep.

Suggestion from me is fine a good therapist, not for medication but to understand why exactly ots happening, if it's physical or mental. It's ok and completely understandable to deal a therapist and talk to your doctor more to not try to necessarily solve it. But to figure why it happing in the first place.

Get a therapist that doesn't try to fix you or try to make you fit into mold. Therapist are supposed to help you discover things about yourself and understand your self better.

This is from my decade's long experience with mental and physical health problems.

I'm not a doctor, and certainly not your doctor. But agree with the comment about anxiety - if the Xanax helps, you are treating anxiety that's keeping you awake, right?

Have you tried running? Or some other tiring physical activity? I'm wound pretty tight and without physical exercise, preferably to the point of exhaustion, it's very difficult for my brain to let go. But with physical exhaustion from physical activity comes mental relaxation.

You know the Xanax helps, are there other times you've had good sleep? Do you know what the conditions were that let you fall and stay asleep?

Also one of my kids got relief by taking Adderall, as counterintuitive as that sounds, helping the ADD helped her sleep even though she was taking literal speed. So please go to a doctor who can evaluate you for anything that might be going on in your mind, you might have room for more improvement than you think. And really - exercise.

Sometimes when I'm sleepless for few nights, what I do is workout, try my finish my work for the next day and get myself really tired. Also try to calm your mind before going to sleep, too many thoughts can keep your brain active. Also try changes mattress, blankets and pillows ( the shape matters as well as the material ).

I get anxiety and have sleep problems too. My good friend gave me some of the cbd thc gummies. I take like 5mg and sleep great. Eventually you build up a tolerance, so for me, every 4 months I take a week off and sleep like shit to reset the tolerance and I'm good to go again. I don't know if it's a legal option for you, but it's a game changer.

Have you tried CBN?
