Breathing problm Male, 26year,lean physic, but protruding belly I have breathing problem from 6 months. Actually it is present the whole  day and daily. when i goto bed usually 2 hrs after dinner, after getting into sleep, suddenly i wake up exactly after 20 mins with breathlessness and feeling of my throat is narrowing,after that i drink one glass water and relax for 2 mins.. Then i can easily sleep till morning. Again in the morning i will feel  discomfort(not pain) in upper chest region and weird taste and also dry mouth and because of that i get up.some times i also do teeth clenching in sleep. when ever i have food(lunch /dinner) it worsens a lot. While having food,uncomfortable in stomach, chest and breath prob increases . If i go and lie back  for some time it goes away. If i have alcohol, the next day the symptoms is very difficult to breath and also eat. When sitting position it is more prominent and i feel tightness in chest and stomach wen sitting. I daily walk for 4kms.
