Wet pineappling works really well for me and makes my curls even better. I have a tight curl pattern though and don't mind the back getting stretched as long as the front and top look good and they do.

You could also put a plastic cap on and then a Turbie Twist. Your hair will probably still be completely wet in the morning.

If you want to wake up with dry hair try plopping until bed time and then using a Turbie twist. Turbie twists stay on really well and your hair won't be disturbed.
