Honestly, you might be better off postponing until you get some good data before to make sure you have a non-affected control sample.
This is my greatest regret with my experiment. It's clear to me when I'm not functioning at all, but reduced function is a lot more subtle. It's also hard to establish a baseline- driving to the store to pick up some alarm stuff before I transitioned, I noticed I was consistently making navigation errors, leading to it taking significantly longer to get there. I found it amusing because of how reliable it was that I would make the wrong choice, but it made me wonder how I would be able to compare cognitive function.
My friend and I are starting the Uberman sleep schedule (six 20-minute naps spread evenly throughout each day) tonight. Have other lesswrongians experimented with alternate sleep schedules? Are any of you qualified medical experts who can give input or advice? Success stories and failure stories would both be appreciated, and I'll keep you guys posted on our progress.
