NOTE TO IRVING: I would still certainly recommend getting the book, the education and ideas it provides are worth it, also try the web research for more details and ideas.
As far as which device, I would recommend just about all of them. For both the ACU-VAC coil and the feedback loop, get the largest ones you can afford and have a partner gently 'brush' your bronchial tube with them, by aiming them at the bronchial tube (following the directions in the book). You can get the mask for immediate breathing difficulties. The personal harmonizer can be worn around the neck for a continuous whole body healing. The rings can be placed over applicable parts of your body to effect a healing.
As far as experience, I have very little, however, I can recommend you to a lady who owns a jewelry and crystal shop who sells the devices in St. Charles, Illinois and can probably give advice: Atala Dorothy Toy at
www.crystal-life.com and 630-443-9101 and 800-871-9985. Also go to the official website at
http://www.slimspurling.com/ and look up the distributors for someone perhaps closer to you to consult with.
BOOKS OF OTHER OPTIONS:
Colloidal Silver by Mark Metcalf
Flood Your Body with Oxygen by Ed McCabe
The pH Miracle by Robert Young
Although I do not have the malady you describe, I have had great results from all these books for my health problems.
Hope this will help
