Well, I think as with most things, balance is the key. The thing is, one thing in short supply for most people in a relationship with an alcoholic is any reasonable way to achieve balance. When the other person is randomly jumping up and down on the other end of the teeter-totter, we tend to either be sitting with our butts in the dirt or get sent flying off the other end.
I think some of these meditations work better once you're in a stable place, rather than trying to figure out how to put out fires. Remember, a lot of these are meant for people well into recovery, but there maybe should be a warning label for those just starting out.
