In my case, I needed to eliminate a medical problem first. My sleep problems resolved when I was diagnosed with celiac disease and I stopped eating gluten. Now any sleep problems I have are entirely because I stay up too damn late sometimes. That's effectively an "emotion management" problem, which for me is alleviated by getting regular exercise, eating well, meditation, etc.
