The best would be be BIREY Noon. Deadliest. I heard VHATMAS works great too. Nowadays it's mostly MULA ko Achar, Mexican Food with lots of bean and Habanero chillie. For quick and fast one, eat some cereal with cold milk, which depends how much are you used to cold milk. You'll have to go take a crap soon though. Simple thing to do as far for a Nepali will be a nice Nepali meal with lots of Indian pickle with green pepper till you sweat and make sure you do not drink water. Watch it work after a day or two. HAHAHAHAHAHA Just my 2 cents experience
