* a sleep tracker. I love AutoSleep - https://apps.apple.com/us/app/autosleep-track-sleep-on-watch...
* Any kind of white noise. I use an air purifier at home, and a little pocket size white noise machine when I travel.
* find and eliminate any noises in your home. Computers, fridges, squeaky doors, etc.
* find and eliminate any lights. Especially stupid power and status LEDs. Bedroom should be pitch black at night. Electrical tape works well for this.
* Blackout curtains
* cheap eye mask
* Magnesium Glycate supplement
* Earplugs- https://www.amazon.com/gp/aw/d/B0015TBGR6
* And finally, a recent addition that I’ve fallen in love with is sleep ear buds: https://www.amazon.com/dp/B0DT9GBFQ2
Although, I would wait on getting sleep ear buds, Anker just announced a new model with ANC and a similar price.
