This song in the link below has been such a blessing to me, just click and listen. Let God fill you up with His Spirit. He will refresh you and strengthen you all over again. Listen to it over and over. We do our self a great injustice by not dwelling in the presence of God. He desires to be with us, and to show us great and mighty things, and we can't do that if we are full of ourselves. Fill us up God, until it overflows!
Below is another version that helps you to simply bask in the presence of God. Just soaking in His Spirit! How I love His presence. Fill me up God!
