=== Gradual adaptation ===

It is possible to transition to E3 '''from E2 or even E1''' by cutting out some portion of the core sleeps and add naps accordingly. However, there are very few sleepers who have been able to transition and adapt to E3 from E2. The gradual adaptation route is often too long in the grand scheme of things, when challenging adaptations to E1 or E2 can be overbearing for any new polyphasic sleepers. It is therefore necessary to stay adapted on E1, or mostly E2 for some months before considering adapting to E3. This can gauge for the personal ability to sustain a reduced sleep total n E2 comfortably, to make sure there is any good shot at E3. An unstable E2 or E1 adaptation will quickly tell the story that E3 may be an unrealistic goal, and an extended version would become necessary.
