From Polyphasic Sleep Wiki
Most successful E3 adaptations come from the cold turkey method. The time it takes to adapt to E3 is potentially shorter than by gradual adaptation method. However, the adaptation to E3 is very harsh compared to E2 or E1, and a failing adaptation due to skipping naps, flexing naps, moving the core sleep and/or underestimation of personal sleep needs can drag out Stage 3 for an extended period of time.
