Living in the northwest, I seem to be affected by sudden changes in the cold humidity. Perhaps this is psychological, but it seems as though I have developed a problem in consuming Ice Water as well. In the past, I have loved keeping ice in my mouth and letting it become "seasoned" to the point where I can chew it without damaging my teeth. This, however, seems to exacerbate coughing now. Has anyone experienced anything of this sort? I think I may have to go "Iceless" :((
