Darren, Hi!
I think that what many of us want most is what we consider 'normal' out of life. With that goal in mind, we test the limits. NO one wants to live in a cage and CH can make us feel 'caged'. If you are running successfully, continue. Triggers, as you noted, usually cause a hit quickly. Sip of beer perhaps. I have gotten that brain crusher before the beer was to the shoulder of the bottle - like two sips. So, yea, for me, triggers are pretty darn immediate. Hours later? I would vote for pollen, weather change, passed by an asphalt truck kind of thing. Triggers are very quick for me.
As long as you are benefiting I would continue with the work out. It is so good for you mentally, right? Frame of mind is pretty darn up there in 'Important Stuff'.
ATB!
