From nightshift to dayshift

I'm working PRN right now. My nightshift tonight was called off, and I was asked if I would work tomorrow morning. I'm not sure if I will be able to sleep at all! Does anyone have any suggestions for making an easy transition, on short notice, from nights to days?..
Sorry, I personally cannot turn my body clock around that fast. I need a good 48 hr window to shift my entire circadium rhythm and even then I would not be fully with it!!

Ugh that sounds miserable. I know if I were in that position, my answer would be coffee, coffee, and lots of coffee.
