You are simply sensitive to how we are really wired. Without the sun<br>
as a cue, individuals vary in circadian rhythm length, with a median<br>
of a 25 hour cycle:<br>

Without my lark husband and kids to wake me, I would revert to my<br>
usual night owl behavior, about an hour later every night, until I<br>
reach a 2 - 3 am bedtime. Then I collapse.<br>

<br>I gave it a try once, on vacation, in happier times, and I was actually much better on a 25 hours cycle. Perhaps I should give permanent melatonin supplementation a try. Of find another, better-syncronised planet or habitat... :-)<br>
