One good suggestion our neurologist had was take melatonin for acting out dreams in REM sleep. I’ve also been hit, had to sleep elsewhere, etc.
I recently learned melatonin is actually an antioxidant, so it’s also beneficial to brain health. no reason an older person needs to avoid, and may have other benefits.
For us, he had to go to 20mg bedtime for it to really work, has to be Long Release (Melatonin LR) so it keeps working all night. Yay, one thing better.
Sometimes he still twitches, mumbles, & gets up to pee, but doesn’t flail out like before.
