I had food poisoning few months back and after that it has been recurring very often. Suddenly,stomach cramps are there ,feeling like defecating. Today had 3 watery loosemotions.I took O2 medicine in the past but did not complete course. Today i was given norflox tz with lopramide and also rantac and omee. But other doctor suggested pan 40 and sporolac sachet with oflox oz. I am confused how to eat the medicines ,and how my digestive system will be fully cured. Can you tell me the correct dose.
