I hear you hun, it's so unnatural. Ive been here for a year and some change and im leaving soon, sadly, the money is great, but my health has no price. Literally, when i start work at 11, my brain, is now ready to go to bed, so I have to fight it. it's such an unfortuante way to live. nights is stressful, but Days is more stressful, but it's natural to me, night time is for rest, not stress, and activity. I rather stress during the day and get a good nights rest than fight staying up at night, kind of stressed at work, fatigued, and get home and still NO rest. the only great thing of night shift is the shift diifferential.
I rather live my life healthy and not slave through work for extra dough. Hang in there tho, it will soon pass. Get your experience, and if you can, move on to something better for you. I see alot of nurses on nights that are just at their wits end, and exhausted but stick it out because of personal stuff.I simply believe that you need to feel healthy to work well.
