Biphaic Sleep - Day 11, 12, 13, 14 - End of journal

Ok, I think I can stop posting about my biphasic sleep experience, unless something special happens. It's my 14th day as a biphasic sleeper, and I think I'm done with the adaptation phase so I'll just relate how it changed my life.

Today, as opposed to my monophasic sleep period, I feel much more refreshed, and have no problems waking up in the mornings. I used to have 3 different alarms to wake me up, and felt tired all day long. Now, I may be groggy for 10 minutes if I gave myself too much or not enough time to fall asleep (and the alarm wakes me up during a sleep cycle), but I'm in an excellent shape the rest of the day; the only times when I'm tired means it's time for me to go to bed.

I now clearly remember dreaming, usually after my core sleep (even though I sometime have weird dreams :). And I'm often hungry when I wake up (?).

My biphasic sleep's schedule is relatively flexible, and I don't have to fall asleep and wake up at the same time everyday (even though I try to be regular for practical reasons). One of the rare penalzing aspects of biphasic sleep is that I'll be really tired if I miss a nap (maybe it'll be different in a few weeks, I'll let you know), but it's just like if you don't get enough sleep when you're monophasic.

I have a lot of extra-free time I can use, since I'm alert all night long: I can work until 2:00 AM without being tired; biphasic sleep also increases your productivity, and I'm often inspired when I write an essay, or during a math test, etc... (better grades).

The only real negative aspect I can think of is that it may mess up your social life. But if it doesn't, give it a shot; it's worth trying, trust me :). Try to keep a regular sleep schedule, at least the first 2 weeks so that your body adapts fully and easily. Here's a great site if you want to try biphasic sleep.
Good luck!

Biphasic Sleep - Day 10

I had a core sleep of 4.5 hours, from 1:00 to 5:30 AM, and remembered having dreams, which rarely happened before. I didn't have any problems waking up, but it was too early to do anything interesting, and I spent the next hour in my bed, reading and listening to music. I don't really want to work in the mornings, so I'll try and fall asleep later, so that I wake up early enough to prepare myself without rushing, but not too early.

I gave myself too much time to fall asleep, and the alarm woke me up when I was entering another sleep cycle, so I felt slightly groggy for the next 15 minutes, but was alert for the rest of the evening (until 2AM).

Biphasic Sleep - Day 9

Sleeping twice a day is the key of success. Even though I had a 7.5 hour core sleep (midnight -> 7:30 AM), I was really tired all day long because of intense physical activites friday and saturday, combined with the lack of sleep yesterday afternoon, and today's family trip. Devin Reams said that having an extra cycle during the core sleep if you skip a nap will make you recover, but apparently it's not my case (or maybe it's because I still didn't fully adapt). It's 5:00 PM now, and I think I'll go and take and nap right away (instead of 6:30) because I'm really tired, and it will give me extra free time tonight (plenty of homework).

The nap was wonderful. I'm not tired anymore, and because it was successfull I'm going back to a 4.5 + 1.5 schedule. I stayed alert the rest of the evening, and was very inspired when I started writing an essay due next week; biphasic sleep makes you more productive :)

Biphasic Sleep - Day 8

I went to bed at 1h30, and set the alarm so that it rings at 9 (after a 7.5 hour core sleep). Anyway, I woke at 6h30 by myself, after completing 4 sleep cycles), and wasn't tired at all. And for the first time, I remembered a dream (plenty of biphasic sleepers say they experience an increase in dream remembering), so I guess it's a pretty good sign.

It's 10 PM, and I'm starting to get really tired. I couldn't take a nap, because I did paintball all afternoon, and now I can't stop myself from yawning every 10 minutes... I'll try and get a 7.5 hour core sleep tonight to try and compensate; I hope it'll work out.

Biphasic Sleep - Day 7

My core sleeps show me I'm still in the adaptation phase: even though I sleep for 4.5 hours and have a lot less problems waking up (compared to my monophasic schedule), I spend 10 minutes in bed, just laying around. And I keep yawning for the next 20 minutes, and feel good after I take a shower. I have no problems of concentration during the day, it's not working so bad after all. But I hope I'll really be efficient and never tired when I wake up, like other biphasic sleeper say they do.

I think I'm addicted now: I woke up 30 minutes before the end of the cycle because of my sister, and couldn't stop myself from yawning for the next hour. Anyway, today is friday night, and I'll try to have a 7.5 hour core sleep (maximum).

Biphasic Sleep - Day 6

I went for another 4.5 core sleep, and it's working kind of weird: I spent 15 minutes lying in bed awake before getting up, and was tired for the next 2 hours. But when I come back and take my nap, I stay alert for the rest of the night until 20 minutes before the core sleep, which was impossible with my monophasic schedule. And having extra free time is great :)

The nap was great; and when I wake up after a 1.5 hour nap, I feel less tired than when I wake up from the core sleep, but I guess it's normal since it's early in the evening, and I still have some energy left.

Biphasic Sleep - Day 5

I went to bed at 1:50ish AM, and was starting to feel tired 20 minutes before going to bed. I set my alarm clock as a backup in case I didn't awake by myself, and it was really useful because I was going for another 90 minutes of sleep. I'll try and not set it too late next time so that I don't start another cycle. I now wake up by myself after my naps, but not yet after my 4.5 hour core sleep, my body still isn't completely used to it. I'm starting to disagree with my mom, who thinks that sleeping 6hours per day isn't enough for a 14 year old, even though I explained her many times how biphasic sleep works. I'll try and do some research to see if it's ''dangerous'' for teenager, but I seriously doubt.

The naps are really refreshing, even if the alarm woke me up at 7:50PM. I didn't have any problems getting out of bed whatsoever.
