As I need to travel 3 hrs per day to reach my office and return home. Past 9 months my routine job. However, past 2 months I am feeling like vomiting sensation in the return journey in the late evening. My daily habits are like morning breakfast ,afternoon lunch (rice. Very rarely I use to have tea in the middle if possible.In the night, between 9 to 10 pm I will have dinner. In the journey, I use to felt sweat coming out, vomiting sensation & uneasiness. If suppose if I eat or drink lightly in the evening or in bus, after get down of bus I use to do vomit. Not only journey, Now a days suddenly after eating anything and after few minutes some watery vomit comes out suddenly.
