Mabey it is a good thing all the extra energy could help your creative side? I have given up 100% on the "typical" sleep requirements and am finally very happy, well rested, and energetic.
I have discovered for MY body, 4-6 hours at night is the absolute MOST I need to feel energetic the next day....any more than that and I am a zombie all day, for me personally, that is the best formula, with a nap here and there in the afternoon/early evening a few times a week as well.... :)
