I had extreme trouble with my breathing for almost 2 years - out of the blue - only 30 years old...no asthma...inhalers didn't work...I'd had anxiety for years...it wasn't that.... I tried everything, but THE WEEK I CAME OFF TAP WATER my problem went away - you should read what they say about what drinking chlorinated water does to you!! I am in Christchurch, Canterbury, New Zealand, and our city council was not forthcoming about the fact that they began to chlorinate our water, and I didn't know. After alot of suffering, and trying everything, the bottled pure water was the answer for me!!! I hope this helps someone...I know ALOT of people in my area who never had breathing trouble before, and now they do!! I tell them to go on pure water, and they have come right! I am so angry at my city council for not telling people they are chlorinating, and not warning about the dangers.
