If it’s the apnea that’s waking you up, the CPAP will work wonders.
If it’s your brain waking you up or keeping you awake, try meditation, incense, or OTC medication.
If your muscles twitch and jerk, waking you up, try skullcap. It’s an herbal muscle relaxer that has been a GODSEND for me!!!
I have both a restless brain and restless muscles. Not just restless legs, sometimes every muscle in my body starts twitching, like they’re trying to run away from each other. Technically, I also have central (AKA: non-obstructive) sleep apnea on top of that, but only if I sleep face-up.
I used to go days at a time without any sleep at all! A combination of Tylenol PM and skullcap works for me. But every person is different, so it might or might not work as well for you.
Or one of Hillary's speeches.
