Go to bed.

You set down the packet of chips and stand up. With a yawn you walk over to the bathroom and get ready for bed. After ten minutes, you step out of the bathroom and climb into the bed. Gosh, it's true, once one is lying in bed, one starts realizing when one is tired. You set the alarm at 8 am and then quickly close your eyes wanting to just fall asleep and have a comfortable night.
