I feel good. I'm about 3 years in now, and I still try to keep my sleep at around 6.5 hours/night (going between 6 hour [4 REM cycle] nights and 7.5 [5 REM cycle] nights). Going up to 7.5/night daily doesn't feel like it produces noticeable benefits, and I plan to keep up this 6.5-hour level. It doesn't feel forced at all. I haven't woken up to an alarm in years. I will stock up on 7.5 two days in a row if I know there's a risk of me only getting 4.5 hours (e.g., if I need to wake up for a flight).
However, despite me feeling good and I think performing wel...
Anecdotally, since reading Guzey's post a month ago, I cut down my sleep from ~7.25 hours (5 nights 7.5 hours + 1 night 6 hours) to around 6.33-6.5 hours (1 night 7.5 + 2-3 nights 6). I found that doing just 6 hours 4+ days in a row led to noticeable tiredness, although I never tried just pushing through and seeing if I can get used to it.
Regardless, with the current sleep load, I feel pretty good, and I plan to continue it. However, I have noticed some rare working memory slip-ups, maybe one per day or every other day, that I don't think were as common before I dropped the sleep, although this isn't severe enough to make me want to stop.
I had trouble initially understanding the level 2 vs 4 distinction. It read as if level 2 was a willingness to lie about object-reality to bring about specific consequences, while level 4 involved similarly lying about object-reality to bring about specific, selfish consequences.
This didn’t seem like the most meaningful distinction, so I wondered what I was missing. These comments seem to describe level 4 as also being concerned with lying about social-reality, which feels elegant? However, we should be thinking of level 4 as being concerned with both obje

I'm glad to help. Since my initial reply 20 days ago, I also started wearing a smart watch to do some sleep tracking, and the watch said that I had a good balance of all the sleep stages.
I figure that even just the present limited data/anecdata is enough to encourage people to try it. Gaining 1 hour or so every day for the rest of your life is such an enormous benefit, and I suspect the cost of exploring this is pretty low (committing to lowered sleep for a week or two). I didn't need much of a "warm-up" period, and I responded well to lowering my sleep of... (read more)
