I tried Uberman once before. I simply couldn't adapt and kept blowing naps (or not sleeping at all).

I'd like to try it again in the future, but this time I would probably try Everyman since my Zeo sleep-tracking seems to indicate I need at least 2 hours of REM (and preferably another hour of deep sleep) to feel normal. I would also definitely be tracking dual n-back performance and seeing what the Zeo has to say like some others.
