Now this is rellly funny because I did act somehow like that but not all of it because I went back to Nepal after more than 9 yrs and man things had changed back home....and yes I tried acting and behaving like before...I mean ate in roadside vendors, drank from the tap and did normal things my friends did........I got so sick that I had a bad stomach and was puking everything I ate...............it took me two weeks to fully recover.................so it is healthy to drink mineral water and avoid street vendorsa for a while untill your body gets used to the new surounding....slowly your body will remember its old habbits.......So after I recovered......I was eating everywhere I could..........and drank wtere even from the street vendors.........Funny thing is When I came back to America I got sick again because of the drastic change....
