Welcome back David and the same to me. A house full of friends and with all of us playing music and a gig Saturday night pretty much wiped out my biphasic sleep pattern so I'm back at it again today, starting with a 90 minute nap in a couple hours (It's 235P right now).
I'm still sorting out whether there will turn out to be an "ideal" time in the afternoon/evening to take that 90 minute nap and how much wiggle room there is in the timing of that, in relation to a nightsleep time of about 1045-11pm with anticipated sleep starting around 1115, reading a bit before I fall asleep, and arising at 345A. I guess that will be one of several good purposes to this log, to see what I find out abt that question.
Any ideas welcome, I've looked at some links for biphasic sleep posted by ScottByrd, they are pretty good...
So, the recap:
11/19 Sunday today, plan 90 minutes at abt 4 or so, then restart!
11/18 Saturday Day 5 NO NAP; Nightsleep 130AM-800A [6.5 hrs]
11/17 Friday Day 4 Nap 4-450P awakened by early arrival of one guest: Nightsleep 1230P-7:30AM [:50 + 7hrs=7:50hrs, but freesleeping, pretty much]
11/16 Thursday Day 3 Nap 615-745P; Nightsleep 1115P-345A [1:30 + 4:30 hrs=6hrs]
11/15 Wednesday Day 2 Nap ("Nap") 800-1100PM then to bed
Nightsleep 1130-345AM---3:00hrs + 4:15 hrs//Total: 7:15hrs
11/14 Tuesday Day 1 Nap (++) 730-1030PM---3:00
Nightsleep 1130-400AM---4:30hrs// Total: 7:30hrs
11/13 Monday Start, with first Nap) 630-800PM---1:30hrs
Nightsleep 1130-400AM--4:30hrs total ending in am: 6hrs

It's great to finally be getting into biphasic sleep! Ati mentioned the goal of finding "a way to sleep which truly produces good rest and health in addition to any time or scheduling advantages" and I really think that biphasic sleep will be that way. It conforms to the body's circadian rhythm better than any other sleep schedule--even monophasic--and I think this form in particular (i.e. aligned with the 90-minute sleep cycle) will be much more efficient than monophasic sleep and much easier to adapt to than polyphasic sleep. The biggest question in my mind is whether this form of biphasic sleep is feasible in the 90+180 schedule (i.e. 90-minute nap and 180-minute core sleep) that I'm trying, or whether a person needs the extra sleep cycle that the 90+270 schedule provides. It might be situational--I could find that once adapted I'm normally energetic under the 90+180 schedule, but if I want to do intense exercise I need the 90+270 schedule. There are lots of interesting questions that I'd love to see answered through my experience and/or the experiences of the others here trying biphasic sleep.
On to the log: having gone to bed at 2am but not fallen asleep too quickly, I had a little trouble waking at 5am. I was conscious from the time my alarm went off, but in hindsight my thinking was very fuzzy. For some reason at 5:10am my mind snapped into focus, I turned off my (still-buzzing) alarm, and from there I was alert for most of the morning. After a few hours I did begin to feel a little sluggish. This was nothing compared to my experiences with polyphasic sleep--the tiredness only became significant twice during the day, and both times were quickly overcome just by getting up and moving around.
My nap at 2:30pm was pretty much ideal. I woke up easily when the alarm went off at 4pm, indicating that the nap's timing had worked with my sleep cycle. I was still sluggish for the rest of the night, but I expect this problem to fade away as my body adapts to the schedule.
