Anyway, I've never been able to successfully do the uberman for more than a few weeks, though I did do the everyman successfully for a few months. As with everything involving messing with the brain, which includes things as simple as caffeine, the results could be disastrous in certain people. As far as I know I'm not such a person. I worry about what things like drunk-inducing-amounts of Alcohol or LSD would do to my brain, which is one of the reasons I don't use such things, but I'd probably be fine afterwards.
