Don't so much wear it "back" as put it on the very very top of your head in as loose a ponytail as you can manage without it falling out in the night. This is called a pineapple.
I can't do my hair in a pineapple, as it is too short. So what I do is plop my hair in a silk or satin scarf. You can find out how to plop here if you don't already know how. This always works for me without fail. Another thing that works for many curlies is to sleep on silk or satin pillowcases.
I hope that helps, and good luck!!
