I have never had this issue. Until I had attended a wedding in a remote village 4 months back. I drank cold Mastani and slept in a/c next day I had strong weezing, white saliva and difficulty breathing. After few days it subsided, but whenever I went for a run or drank even moderately cold drink/water wheezing starts and I have difficulty breathing. Till now after 4 months I'm having the same underlying problem. Though it's reduced a lot but not completely gone. Doctors gave me antibiotics and called it an allergy. But nothing helped.
