Managing the neurotransmitters

I just listened to the your podcast on neurotransmitters, and really loved learning more about these chemicals in the brain.
I was wondering what tools you suggest if you release the chemical and then realize what is happening. For example: fly off the handle after your kids pick your ex over you, I understand that Oxytocin being released, once it is released is their something you can do manage it, or does it always need to be recognized prior to the incident?
