I LIVE IN THE DESERT BY LAS VEGAS. I USE A SWAMP COOLER AS I CAN NOT AFFORD TO USE MY CENTRAL AIR.I CHANGED THE PADS EVERY YEAR. DO I NEED TO AD SOMETHING TO THE WATER RESIVIOR TO KEEP ANY POSSIBLE MOLD AND I DON NOT HAVE TO SMELL IT.I CAN NOT SEEM TO QUIT SMOKING, ONLY 5 A DAY. IS THERE ANY GREAT IDEAS FOR QUITTING?
