The reverse gradual adaptation method was also once a popular way to adapt to E3. The strategy is to first attempt Uberman and then jump into E3 after a few days, taking advantage of the large sleep pressure from Uberman. By anticipating the incoming Uberman crash, one can then choose one of the Uberman naps (typically the one around evening hours) to become an E3 core with a desired length of choice (3h or 3.5he). While this method has been discouraged recently, it did have some success over the long history of E3 attempts.
