I did this for a year in high school (bi-phasic, 1.5h + 4.5h). Had to stop because I was disrupting my parents at night, but I had very good results overall. Felt like I had more energy during the day and enjoyed surreal relaxing times awake at night.<p>One thing though: I had a really hard time waking up from the short nap and had to have my girlfriend call me to wake me up every day. If you don&#x27;t have a (girl&#x2F;boy)friend to help you with this, or a very aggressive alarm clock, YMMV.<p>Another friend is doing a similar cycle right now and it&#x27;s the same for him ... he has some friends (&quot;accountability partners&quot;) who will call him to wake him up daily from his shorter nap and I think they talk about how their day went and then hang up.
