I am also having the same issues. I started working nights (7p-7a) 2 months ago and the first few weeks I was doing okay however now I am not able to sleep on my nights off, I stay up all night until the sun comes up. I fall asleep sometime around 7-8am and I sleep into the afternoon, it's really affecting my personal life and is very frustrating because I can't do anything during the day Bc I'm catching up on aleep. On the days that I work I usually have no problem sleeping when I get off in the morning but I do not want to be up all night on my days off, anyone have any suggestions? I have thought about leaving my job due to this. I have tried melatonin and Benadryl it makes me drowsy but doesn't keep me asleep.
