I work nights every other weekend- 12.5 hour shifts, and days in between. Sleeping is difficult and confusing. I sewed a dark blue, nearly black, sheet to the back of my curtains, have the fan on, wear a sleep mask, and sleep for 3-5 hours. I’m tired with 3, but feel pretty good with 5. Used to be I’d do 3 nights in a row, but have been cut to 2 nights for which I’m grateful. I need the additional hours from the day shift for insurance.
