It started by occasionally falling asleep when putting my son to sleep, and when I&apos;d wake up I&apos;d compensate by staying up longer.&lt;p&gt;After a while I realized it works very well for me to got to sleep for a couple of hours around 8 when he goes to sleep, and then stay up for a few hours before going back to sleep - I usually feel very mellow and relaxed when waking up after my first sleep period, and then very energized after I&apos;ve been up for a little while. I get far more done this way than by trying to make myself work on stuff at the tail end of a long day. In fact, I&apos;m coming out of my &quot;mellow and relaxed&quot; phase after my first sleep period right now, and is about to start working on a project...&lt;p&gt;Sometimes I end up &quot;exploiting it&quot; by cutting my total number of hours of sleep drastically, and feel little ill effect as long as I compensate with sufficient rest the following evening.&lt;p&gt;Occasionally I&apos;ll combine this with a 30 minutes nap at lunch time. If not I&apos;ll usually spend that time meditating instead.</text></comment>
