During shift, plenty of water and good stretches when you can.

after shift you've nailed. Sleep!

plenty of others have suggested a massage appointment, do that too someday.

I hope your schedule gets less hectic, and your self gets the pampering you've well earned.

Yoga, herb, and a hot soak in a tub or hot tub if possible. Nothing will replace sleep though, try to ensure you get enough rest in the next day or two. Going much longer than you have already is very dangerous in all sorts of ways.

Pedicure and foot massage!
or
Hot tea and a good book....

Eat clean. Prioritize sleep. Exercise-HIIT, strength, enough but do not overdo it. Don't abuse bad shit. Chill.

Works for me.

Quiet time, meditation, a nice shower, a nice cup of tea, a wonderful conversation with a good friend, agnostic.com, a good book, writing, art, favorite music, a fun movie or TV show, a relaxing walk

Sleep, yoga, hot shower, bath, walk, write, read, color, find nature, Chase sunsets and/or rainbows.

sleep. i am no good at it, though.
