When doing my PhD I used to work from ~13:00 to 5:00 de next day (the rest was sleep). I now wake up at 6:45 after 8h or so of sleep. The surprising thing is that I cannot tell you how this affected me because it did not. I did the switch a few times easily. Now that I think of it, I have never been bothered by time zones either (I used to constantly travel worldwide east and west bound for a few years). I never had problems to sleep (neither in time nor quality) This maybe means that some people are not impacted to much by dlrrp cycles and that just giving a try to something else may be a great experience (I loved my owl cycle, though I had obviously zero social interactions at that time)
