Just get really drunk first. Kidding!!
I am about to go off orientation too... my preceptor has been backing off gradually so that now I'm almost on my own anyway except when I need help or am super busy and drowning. You may want to consider this if you aren't doing it already, and if you think it would help. Some "testing out the waters" days.
Although I would like to be able to observe her more for the last two weeks, it also helps to get released gradually because I don't really feel like I'm getting cut free all at once. Since I know that they will still be there for my questions, it will be almost the same as now (unless my first day off orientation is crazy busy which Murphy's Law states that it will be!!).
I think we just have to hang in there, prioritize, and ask when we aren't sure about things. The asking gets old but my patients are #1 so I don't care. If I feel like I'm bugging someone by asking a question (possibly for the 15th time) I try to add some humor so it's not so much drudgery. I also have made some checklists for things that I find just aren't "sticking" so I can remember them (actually everyone else keeps asking to see my checklists
Everything should continue to fall into place! As Deb wrote, let us know how it's going. You and I are on the same schedule so I'm sure I'll be on here crying, complaining, or something!! LOL
