Hi - have you done a good colon cleanse? I couldn't handle the ozone water before I did it, and after I have been able to drink with no problem. Actually I had done a ton of colon cleansing but I wasn't able to handle the ozone water without having big time problems until I did a Colon Cleanse with Oxypowder . I will say that my ears still get itchy even if I'm just drinking the ozone water - without ear insufflation. I still can't handle ozoning my ears as it keeps me up at night for days from the itchiness. But since the cleanse and after drinking the water for a while, my ears are itching much less now than they used to when I drink the ozone water.
