Russ, a thought just occured to me. Those aircraft flying over may be releasing plenty of aldehydes. Many here are aldehyde sensitive. Candida produces plenty of aldehydes. Are you sensitive to perfumes and colognes and cigarette smoke? Those also have plenty of aldehydes. If so, have you tried taking some measures to detoxify from aldehydes? Do you take a molybdenum supplement?
