Let my comments be a side-effect caution: I began the ramp up treatment of 3 drops of 35% peroxide and adding a drop a day doing this only one time a day. I got up 13 drops, stayed on it a few days, and decided to go back down a drop a day. When I got down to a low dose, I started having sudden anxiety attacks and depression which I thought were due to losing my office due to sickness and not being able to work and my wife working now all the time to make up the difference and a separation anxiety from that. For two weeks it has been a problem and it hit me hardest last night. I had bad anxiety, but realized also that I had lightheadedness. I thought that perhaps I was hyperventilating so I breathed in a plastic bag (could not find paper) for several minutes and then again, and the overwhelming anxiety lifted completely. I was surprised that worked so well that I would recommend it to any sudden anxiety that appears to see if it would help despite not recognizing it as hyperventilation.
