These are some of the things I have noticed.
Firstly, the more I do it the easier it gets. It's also incredibly addictive. To go into that space and FEEL a powerful feeling of well-being washing over me is a potent drug. And because it feels so good, it's easier to notice when I'm reacting in a way that doesn't feel good. And from there it is easier to take my little hop into "feel good" land.
