You sleep at your best when you follow God's law. If you find yourself waking up in the middle of the night for not reason, check with God. If you find yourself waking up every morning doubting a decision you have made, it's because God is still not pleased with your direction. Try adding 15 more minutes in the morning and in the evening to meditate and worship with God. You'll see how the decisions you make in the day will help you sleep at night.
