Sure, yoga helps me to just relax enough so that I can sleep properly during the night and that…then I get out of that cycle of not sleeping, and you know, not eating properly. That seems to help a little bit with me. M: Well, not sleeping is the first thing that happens to me if I'm under stress. And it's only quite recently that I've realized that the best thing to do is not try to sleep.
