Hlo sir/maam. I think I am suffering from stomach problem. Firstly when I used to eat anything and after completing my meal after few minutes my stomach used to feel sour and sour water was coming out from my mouth. But from last few days I do not even feel hunger to eat and it takes good 30 minutes to complete my meal which could have been completed in 5 minutes. And now during having my meal I feel like vomiting, and in morning when I go washroom for getting fresh as long as I put water in mouth I start vomiting. I do smoke please help.
