Heather, I love the Pac Man visualization. I've used it myself in the past.

Melatonin, magnesium and I'm also on gabapentin for nerve pain. (It makes me sleepy). I wear a cpap at night otherwise my sleep would be interrupted constantly. I can't eat late, or drink tea before bed. A cool room with extra blankets, and an extra pillow for nights I have trouble breathing. I also wake between 3 and 4, get up make coffee and return to bed around 530 for an extra hour off sleep. We've been getting up at 4 AM for almost 40 years for my husband's work schedule. . I guess it is a habit now. Finding what works for you is the answer.

80% is waaaay too low.

I started sleeping much better after I started my medication for IPAH. With IPAH my oxygen saturation levels are fine. I am more careful with not stressing and don't drink caffeine so I sleep better (7 to 8 hours per day). Otherwise I feel really sleepy during the day.

I don’t always get good sleep in the bed…..but I can come out to my recliner around 6AM…..snuggle up under my soft throw & be in La La Land in no time flat 😃🥲😃😃
