Bi Phasic Sleeping

Now that I don’t have to get up for work at a fixed time, my body seems to be heading towards a biphasic state; which I am told is natural for humans and what our ancestors did.

Typically this means that I go bed about 10 or 11pm and sleep for a few hours; typically 1.5-3 hours correlating to 1-2 REM cycles. Get up and work for a few hours and then head back bed for another REM cycle or sometimes 2 if I am really tired. This means I am naturally getting 4.5-6 hours sleep a night and not feeling particularly tired at the end of it.

I have to admit, this is a nice state to be in some respects, but it isn’t helpful in others as I am out of sync with my girlfriend who is on a fixed schedule with regards to uni.
