I've only been a nurse for 7mos and love nights! I only work 3-4 days a week. The first couple of mos is hard, but stay positive and I agree w/ all the other reply's. Rest if you can't sleep, turn your phone off, and drink plenty of water and exercise. If you start to get tired, get up and stock carts, replace gloves, etc. It's better money and less stress to me. It also helps you to think critically about when to call the doctor, but when you are at your wits end, just remember, the doctor, nurse, etc, is responsible for this patient, 24hrs a day, 7-days a week, so your priority is the patient always! I wiah you well!
