My husband and I are doing the H202 3% food grade inhalation therapy every night for about 6-7 hours for over a month. We have noticed significant bloating (bigger belly) and it isn't our diet. We do not have "large" bellies. Is it possible for the H202 inhalation (via humidifier) to cause bloating? Is this a concern? We are happy with the results, otherwise. Thank you!
