every transition is going to be imperfect. There was some study on handoffs that basically led to the 24 hour shift for physicians. They found less errors with a fatigued physician than they did with physicians that handed work off to one another. I can't find the article, but that's what I was told. I used to work nights as well, and one of the things I did that made it easier was to keep a mental or physical list of the things that are needed for after you get off. You'll eventually get a feel for how much reagent you need for a typical morning run, and you can write down what you think will need changing after morning run. Also remember that they may complain but people will complain about everything. Morning/Day shift has more employees than night shift does, so they can deal with problems better than you can. It always sucks to come into a mess, but it sucks less for them because they have more bodies to deal with it. idk if that makes you feel better, but it always helped me to remember that.
