I am having a feeling that my breathing is not sufficient, hence have to take a deep breath at least once in 10 secs. This affects my normal sleep. I am suffering from this problem at least for the past 4 years. I had consulted a pulmonologist sometime back and had done the pft test also. The pft result was ok. I had taken many medicines including deriphyllin tab but in vain. Your advice will be very much appreciated. Thanks, Sasidharan
