Sure - you can explore using a simple, safe, and easy to employ breathing technique when these 'episodes' come about in your life... One that I know of is called 'equal breathing', which simply entails focusing on inhaling and exhaling for the same number of counts/seconds (recommended is 4 seconds):

Not only can this be beneficial physiologically, but what you are accomplishing by intentionally directing your focus/attention to your body & controlled breathing practice is that you are effectively shifting your conscious awareness away from the disturbances that have surfaced - whether it be the physical feelings of agitation and/or unwanted physical mind activity ('chatter')... For instance, if your physical mind was acting erractically and generating anxiety-inducing thoughts - the act of shifting your awareness to your body/breathing and importantly within yourself (your core), this will draw conscious energy away from the head (physical mind / brain) region and effectively de-energize that unwanted mental activity going on up there...

If you find that you're interesting in exploring this, than I would say try to make it a point to test this out for maybe a period of 2 weeks or so and then reevaluate how you feel and whether or not you've found that it has helped you and made a difference - you know? I would love to hear about your findings...
