Please choose the correct ending to complete the given sentence: Health: [header] How to get up in the morning [title] Avoid hitting snooze. [step] This will help you avoid hitting the snooze button over and over again, and you'll be forced to get out of bed to turn the alarm off. [substeps] Set the alarm on a bookshelf, by the door to your room, or by a window.

Ending1: Preferably, you should set it to go off at least an hour before you want to go to sleep. [title] Use the snooze button as a reward. Ending2: Make sure the alarm is close enough that you'll still hear it when it goes off. [title] Turn on the lights as soon as you wake up. Ending3: Try not to hit the snooze button multiple times, or you'll start to feel groggy. Setting your alarm a few moments before the alarm goes off helps you actually get up and return to sleep early. Ending4: This works best if you normally wake up at the crack of dawn, so it won't be as important to wake up more gradually. Turn the alarm on a clock nearby that adjusts to this.
