Yep, did the Transcendental Meditation shtick in the early 70s. Didn't stick with it very long. Never met the Maharishi Yogi, but met people who did. The guy was apparently so calm he barely had a pulse.

I have had sleep issues for the last several years. I fall asleep within 5 minutes, or less, of going to bed at night. But when I wake up during the night to go pee, I sometimes can't fall back asleep when I return to bed. Drives me fuggin' nuts. Some times I lay awake for as much as 2 or even 3 hours. Sleep issues are one of the reasons I retired 4 years ago. So I try meditation to fall back asleep. And it works, but not always.
