How do yall get ready to sleep?

Ever since being sick a few weeks ago, my sleep has been shit. I’ve tried everything from turning down the temp, getting more sun in the day time, melatonin, medicated sleep aides, turning off electronics, getting out of the bed room and reading when I can’t sleep, removing caffeine, exercise but not to excess etc. Nothing is helping. Even went to the docs and got tested for sleep apnea and that came out negative as well as bloodwork which was nom. I’m not stressed out with work or personal life.

I’m so tired. At the most I would get 2-3 hours and be very fatigued all the time.

I’d appreciate any tips.
