Took night shift 7p to 7a a year and a half ago just to get into ER. I don't have any trouble (usually) staying awake and alert while at work. My problem is all I want to do is sleep when I am off work. I have been known to sleep for twenty straight hours after getting off shift. I almost always feel groggy and depressed. Except on vacation of course. Is this normal. Do other people feel like this when working nights or is there something wrong with me. I have a great home life and supportive spouse so no complaints there. Thanks for helping me out with this.
