My experience is the same. If I constantly change it up, I have no problems.
On weekends I try to hold to a more timezone specific schedule, but include odd naps at odd times to sort of keep the schedule of broken sleep.
One other aspect I've noticed is I used to feel more tired and people would always comment on how tired I looked. Now I feel much more awake and in the moment, although honestly I have no idea why this would matter.
I think I'm always kept at a constant state of having slept not all that long ago, even if it was a short period of time, and that helps? This is guessing.
The other aspect is, I try to keep my sleep intervals at an hour 30. so, 1:30, 3, 4:30 hours. Not sure if that has anything to do with it, but easier for me to wake up when I do that.
