I Suspected That I Had Mild Dysentery And Took 2

I suspected that I had mild dysentery and took 2 dose of Norflox Tz (1 at a time). I am already feeling better now. Is it okay if I do not take any more Norflox or should I complete the course for three days as I believe that Norflox is an antibiotic ?
My symptoms were slight cramps in tummy, sticky stool and frequent visits (3 times) to toilet. However also note that I have just travelled back from India to Canada where I live. Thanks
