I have a question...I got a phone call today from a family friend who just started their residency in Florida. She is having problems staying awake for 24-36 hours at a stretch.She works 24 on- 36 off....but after her 24 hrs on...she still has charting to do and that usually takes an additional 2 + hrs .She is sleepy ( extremely) of course after 16 hours...so...How in the heck do these residents stay awake for 30 hour stretches?Anyone have any helpful pointers I can share with her?I hadnt really thought about it till she actually brought this up.
