Despite it appearing to be an easier version of Triphasic with an extra core, many reported difficulty falling asleep in some sleep blocks when adaptation first begins. As time goes by, it then becomes increasingly difficult to wake up from the cores. This may be due to the distribution of sleep blocks, which keeps [[Sleep Pressure|homeostatic pressure]] relatively low.  

Despite it appearing to be an easier version of Triphasic with an extra core, many reported significant difficulty falling asleep in some sleep blocks when adaptation first begins. As time goes by, it then becomes increasingly difficult to wake up from the cores. This may be due to the distribution of sleep blocks, which keeps [[Sleep Pressure|homeostatic pressure]] relatively low.  

These symptoms may result in [[Oversleep syndrome|oversleeping]], as iwhen they finally manage to fall asleep in a core as sleep pressure becomes high enough. For this reason, it is advised that if it is impossible to fall asleep for a core after lying down for ~20 m, one should wake up and wait for the next core sleep rather than trying to fall asleep and risking SWS wakes. As part of a typical 90 m core sleep, failure to fall asleep fast enough will result in mid-cycle wakes; this makes adaptation to QC0 very challenging, and inexperienced sleepers should '''NOT attempt''' this schedule. '''[[Meditation]] methods''' as a way to relax and aid the body in preparation for sleep are recommended at an early adaptation stage for this schedule.

After lying awake for more than about 20-30 minutes, one should wake up and wait for the next core sleep rather than continue trying to fall asleep. Failure to fall asleep relatively soon will result in mid-cycle wakes, which makes adaptation to QC0 very challenging, in a different way from most other schedules. Beginners should particularly avoid this schedule, as experienced polyphasic sleepers tend to fall asleep more easily. '''[[Meditation]] methods''' as a way to relax and aid the body in preparation for sleep are recommended at an early adaptation stage for this schedule.
