I tend to do the 48hr sleep reset - I'm not sure if it's completely healthy however it does ensure I get a solid night sleep afterwards and for some time after

I tend to go with the flow until my next day off and then try to reset.

i usually either force myself to stay up or go to bed early, depending on which direction my sleep schedule is skewed. i'll take melatonin if i need to sleep early, and i'll provide lots of distractions if i need to keep myself up. then i try my best to maintain good sleep hygiene from there--keeping the room dark, quiet, and cool, powering down an hour before bedtime, and sometimes meditating or journaling to calm my mind before bed. another thing i've found helpful is trying to limit bedroom activities to sleeping and sex. that way once i get in bed, it tells my brain it's sleeping time. of course, i inevitably end up messing up my sleep schedule every once in a while, but this has helped! i know some people like to stay up all night to reset, but i try to avoid that as the sleep deprivation can really make you sick and can lead to a crash.
