My children came down with coughs many years ago. They coughed for 10 months. The reason was our water company had started putting Chlorine into our tap water supply for the very first time in their little lives.
Bottled water to drink put in juice etc. = no more coughing.
This all happened to them 9 years ago.
They don't cough any more and do not need to use medicines every day.
The really scarry thing is after seeing their docs many times they were saying they were becoming asthmatic and gave them asthma drugs.
HAH! and to think all they needed was to get away from the chlorine tap water!!!
Check into it. Maybe all a lot of other people need to do is stop drinking chlorine tap water.
Surely my children aren't the only ones in the world with this sensitivity/allergy to chlorine tap water.
