You will likely do best if you find the exercise level that causes a return of symptoms and limit your exertion to just below that level. The Buffalo protocol does this limiting from a pulse rate perspective. If you have the resources to purchase an exercise pulse rate monitor, you can likely find your pulse rate limit.

For me, exercise does not cause a return of symptoms of headaches. My head aches just come and go as they please.

There is a great benefit to learning to limit the triggers that cause emotional overload. One can also develop a thought process that allows one to accept the reality of a world with ample emotional triggers that do not need to be resp0onded to. Very few of those emotional triggers will respond to a reaction. So, if you can't do anything about them, why fret about them?

Whether you develop you own philosophical perspective or hold to a religious perspective as I do, either way, the calm is worth the effort.

My best to you.
