@pb50 You might enjoy reading about the glymphatic ... during non-Rem, Stage 3 deep sleep

Thank you for that!! Looks quite interesting, and has me curious about if/how LiO could be involved in or interacting with that. Again, it's on those hapless rodents but promising.

Hopefully the focus on sleep will help, including any associated benefit from LiO. Speaking of which, I've just last night started splitting the now 10mg dose morning before breakfast and night before bed. Hoping that makes for better sleep and more stable blood LiO level.
