Hi. I am 5 ft 5 in and weigh just under 100 lbs and so I try to drink 6 1/2 - 7 cups of water daily from our Berkeley gravity fed water filter. It seems that whenever I drink the amount of water I feel I should be drinking, I cough, but if I drink only drink a very small amount of water, I don t cough at all. Since I ve had this cough for 2 years now, I m getting desperate on how to get rid of it but surely removing water from my diet is not the answer! Oh, never mind about the water. I ve not been drinking much water but just now had a coughing fit. Sure would like to know what to do about this cough though.
