It has been a few days since I stopped polyphasic sleeping, and I am facing some consequences from suddenly changing back to monophasic when the adaption was significantly in progress.
I've been waking up late, and not staying up that late. Today I slept 12 hours, from 1am to 1pm. This must be the third day of not sleeping polyphasically and I am still sleeping hours longer than I should to make up for lack of sleep, which continuing the naps would have done.
There are 2 paths, one straight ahead to polyphasic, and one turning off to monophasic. I was forced to take the monophasic path. Both would do the same thing, make up for lack of sleep, however one would obviously bring you out on polyphasic and the other on monophasic.
So by taking the monophasic path, I've been sleeping 3-4.5 hours longer than I normally would to make up for lost sleep. Even now, I am still tired and had difficulty getting out of bed. Actually I always have difficulty getting out of bed, one of the reasons I wanted to sleep polyphasically.
