Should we use this thread for general biphasic discussion? If not I'll delete this post and post it wherever is more applicable.
Anyways, I decided to go biphasic a week ago, did it for two days, went to my parent's place for Thanksgiving, got sick, and broke it. However, I'm starting it back up again starting yesterday.
The schedule I'm going for is a 90 minute nap from 7-8:30, and 3 hours of core sleep from 2-5 (two cycles), reducing my sleep to 4.5 hours. I haven't had any trouble with tiredness, aside from 15-30 minutes before my nap (like right now!). I've found that my naps seem to work freakishly well- yesterday, I just couldn't get to sleep, I'm currently living in the dorms so it was pretty loud. I decided to go over and put one of my favorite CDs to fall asleep to (Sigur Ros' Takk, brilliant album, brilliant band), went back, and I can't remember hearing the second song on the album. Next thing I know, my alarm song is going off on my computer. Look at the clock, hour and a half has passed and I'm completely awake, refreshed, and ready to go- though I didn't feel like I slept at all. It seems that as long as you nail the 90 minutes you wake up completely refreshed- just watch out if you go two hours.
Not all is perfect, though, my alarm didn't go off this morning so I slept in an extra 3 hours
I'm pretty sure I just didn't set it right, so that shouldn't be a problem from now on. It all seems to be working great so far though, I'd love to hear other peoples' experiences.
