How do you unhypnotize someone?

Say to yourself something like this: "Now you will begin to wake up and will waken gradually as you count to 5. When you awake you will feel as before, refreshed and alert. One: Starting to let go of the sleepingess. Two: Beginning to awaken, eyes not so heavy. Three: More awake still; eyes lighter. Four: Eyes beginning to open, mind clearer, sleepiness almost gone. Five: Eyes open; wide awake now, alert and refreshed!" and then go hypnotize someone
