Dear doctor, I am suffering from a stomach trouble since 2,3 yeras. When i eat certain food like cold salads, sausages, drinking nescaffe, mostly food preapred just taken out of the deep freezer immeadiately i get a severe somach pain and have a loose motion for one time. Then it stops. As i am working as a tour guide i am always out and everyday i have to eat in hotels in buffets. It is very very difficult for me to select food because we have to eat what is available. When i am at home i eat hot food and then i done get that problem. Onje time i was give colifaginapro by a foreigner and it helped me a lot. But in srilanka colifagina pro in not available. please advise me a similar medicene where i can get easily. Is bifilac similar to colifagina. Thank you.
