I do not get much natural sunlight. I sleep beside a window with no curtains, and which faces the rising sun. Despite this, I'm able to go to sleep when I should pretty consistently.
I've tried to keep myself on a regular daytime schedule using sunlight but I found myself unable to go to bed and get up at regular times. Even with less natural sunlight, I'm consistently more rested and alert now than when I got sunlight. Even taking melatonin at night and setting numerous alarms, it was a constant, taxing struggle.
When I'm up nights I'll leave the lights on in my room to help regulate and to help me feel awake. I'm also very very consistent with my caffeine intake (same amount every day, at the same time relative to when I wake and sleep).
Regarding jetlag, I haven't traveled recently or had such drastic changes of schedule that would interrupt my circadian rhythm enough to be of any detriment.
