I used to be a ward nurse and work shifts including nights - thank goodness I don't do shiftwork anymore! I used to find starting nights ok. I'd get up at my normal time the morning before starting my night shift, do whatever that day and not sleep before going off to work. I'd get home somewhere between 8 and 8.30 the next morning and go straight to bed. I didn't have blackout blinds (just drew my curtains) or need white noise or anything - it's usually very quiet by me but I would be that tired I could sleep through anything, including my neighbour doing building work! I'd get up about 4 and keep that routine going until the end of my nights. I'd get up about midday after my last night shift to try and get back in to a day routine (that was the bit I struggled with).
I drank a fair bit of coffee but didn't drink enough water, I often felt dehydrated. I couldn't eat on night shifts, others would be sitting there eating snacks all night long but I always felt sick. Sometimes I'd eat my sandwiches either before driving home or when I got home, before going to bed. On my first ward, I'd take a book to read on my break but on my second ward (which was busier overnight) I'd just choose to work through my break. When I was a student, my mentor would tell me to have a sleep but I just felt worse for doing that so wouldn't.
Driving home was horrible. I had no alternative, rubbish public transport (heard about colleagues who got on trains and buses and slept past their destination, one was visiting her boyfriend a few towns/cities away, ended up getting woken on the train a couple of hundred miles past her stop!) and far too far to walk - about 20 miles. I used to drive home with the windows open and sing along to the music.
I hated it (but that could have been due to the fact I was constantly swapping, we could do four 11 hour nights, finish Saturday morning and be back in on two 14 hour days from Sunday morning). I had some colleagues, who mostly worked nights, who loved them. I would always happily swap night shifts for days with my colleagues.
