Abstract: A breathing control device formed from a regulator having a stem opening and aperture opening. The regulator having a mouthpiece for inhaling and exhaling into a diverter bag coupled to the regulator. The stem opening and aperture opening available to control the amount of ambient air drawn into regulator to regulate the ratio of carbon dioxide to oxygen level drawn from the diverter bag to assist in treating panic and anxiety attacks associated with hyperventilation and migraines. The diverter bag retaining the exhaled breath expelled by the individual for reuse, the aperture opening can be capped to limit all ambient air through the stem opening. The diverter bag becomes a visual focus as exhaled breathing causes the bag to unfold with thought provoking indicia.
