I understand your concern
It's important to keep hydrating yourself with electric powder whenever required until you lose water through stools. Antibiotics are not generally necessary if you stool is watery and does not contain blood and mucus. Eat light food such as rice and dal. The headache may be due to dehydration. It will settle down  with above measures.

                                                        Sir, I also suffer from migraine headache. I doubt if this headache adds to my pain. Can you suggest antibiotic for quick recovery?
