Sounds like white coat syndrom to me. When practicing you are relaxed and calm, but when the bird is truly on the way you get excited. Like a person who takes their BP at Walmart and it is fine, but they head to Dr and it goes sky high. I'd say this the water is great and I store my calls in mouthwash so they always taste good (mouth waters) and fresh when I put them in and secondly kills germs. I agree the water helps a buch. Concentrait on breathing through your nose and not mouth breathing. Mouth breathing will increase the dryness of the mouth and call.
