Fascinating article, there is so much insightful information about the lactic acid connection with panic attacks...I had never heard or read about this. I realize that quite often I am a shallow breather, and I don't hydrate myself as much as I know I should. I also live in south Florida, and dehydration is pretty much immediate once you step outside during the spring/summer. Instead of my body producing enough ATP, it is producing lactic acid instead.
When I go to the gym, without taking my beta blocker/benzo cocktail, I hyperventilate a lot as my cardio training increases in intensity. This hyperventilation is what I bet leads to the panic attacks, because it creates all that excess lactic acid, in addition to low carbon dioxide levels in the bloodstream. Moreover, I wonder if this lactic acid is connected to body aches/mild chest pains that I occasionally get (I've gotten the barrage of tests from doctors and have been cleared of any health abnormalities, plus I'm 24).
Anyway, going back to the topic of this thread, I do indeed find that a beta blocker is helpful for keeping panic away, particularly in moments that one anticipates will be stressful or anxiogenic. They are very safe, and at low doses have virtually no side effects!
Thanks for this information Never-Quit!
