Cater: I had no idea that there was an official term until I decided to google it. I kinda just fell into the cycle. But no, it doesn't bother me. Actually, I think it suits me very well.
I'm the type of person who wakes up after 4 hours or so. And though I can pretty easily get back to sleep if I needed to, I feel wide awake and refreshed. So I kinda just ran with it.
But then I thought that my lack of sleep is what was making me tired in the middle of the afternoon. But instead of changing back, I just embraced taking a regular nap during that time.
Now I sleep from 3-7 am and 3-6 pm on most days. It's not on a rigid schedule or anything. If I feel tired, I go to sleep. Simple as that. But now that I don't go immediately back to sleep when I wake up 3-4 hours later, I sleep pretty much twice everyday. (That's not to say I can't stay up longer than 8-10 hours. I went roughly 40 hours this past Halloween weekend.)
It's been fantastic! During the Summer and Fall, I saw the sunrise and sunset everyday but without the grogginess. I also naturally wake up and eat a meal twice a day. Sometimes I'll have two breakfasts (my favorite meal). I also get up earlier than damn near everyone and when I go out in the evening or at night, I'm more rested and thus mentally and physically sharper than everyone else.
I also don't get annoyed with women sleeping in my bed anymore. After I Super Smashâ„¢, I leave her to pass out and I go take a shower and do my own thing for a while. When I come back, she's deep asleep which means she's not rolling over or changing positions, allowing me to pass out all the sooner. And almost always, I wake up earlier than her.
Best of all though, is the amount of real quiet time that I get. Those twilight hours when everything is dead silent outside is bliss. When it was warmer, I use to go out to my back porch and work or read or just sit and relax. Can't wait to be able to do it again.
