Help with sleep?

I’m usually ok getting to sleep, but I wake several times during the night and, of course, don’t feel refreshed in the morning. Melatonin didn’t help. I’ve had a few sleep studies, all clear.

My dr put me on amitriptyline a few months ago to help with staying asleep/sleep quality. It’s helped a bit, but not enough. Has anyone tried anything else that has helped? Note I will be checking with my dr before stopping amitriptyline/trying something new, just looking for other options worth discussing with her. Especially something suitable for long term use, as a lot of pharmacological sleep aids don’t seem to be.

I’m already doing a lot of the ‘lifestyle’ things that help with sleep, so I’m more looking for medications or supplements that have actually helped other mecfs people. But if you have a weird and wonderful habit that gets you amazing sleep, please share!
