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.
Feel free to discuss further
