This meditation is to help you fall asleep faster and stay asleep longer throughout your night. Remember, there's no wrong way to meditate. Don't judge your meditation practice. Instead of wondering how long should I meditate for?, Instead let it be what it it needs to be and remind yourself that there's no wrong way to do it. With practice you'll feel more and more comfortable with meditation, and you'll be able to meditate for a longer period of time and be able to feel more clear-headed as you meditate.
