It's a daily schedule! And yes, if I notice cannabis to really make it too hard, I'll try without. It's quite likely as it affects REM sleep length. I've gotta try it out, though.
I'm quite honestly really intimidated by the Uberman schedule. I work out pretty regularly and I feel I need at least a little sleep to recover, other than "washing and rinsing" my brain. Perhaps in the future I'll try it, but I'd rather start here!
