Have you seen a sleep specialist? There are many strategies, medications, and supplements that could possibly work for you. After struggling with sleep for years, and researching benzodiazepines (I was on lorazepam which my pcp wanted me off of) I have found a medication that works, low dose of mirtazapine.
I have friends who swear by gummies, ashwaganda, magnesium glycinate. the key is finding something that works for you.
Good luck!
