This whole thread has a lot of info in it, but the main point is this - we suck at breathing, don't breathe properly and are remarkably easily knocked out the "calm awareness" mode.
It's sometimes best to work at this other way around, like with anger management, e.g. don't try to improve your breathing, but try to be more concious of when your breathing and mental state go to sh*.
