Thanks for writing your query.
Antibiotics usually disturb the normal flora of useful bacteria present in the intestines which help in the process of digestion and absorption.
After reading your post, it seems that your symptoms are due to side effects of antibiotics.
I would advise that you should take a probiotic
daily for relief.
40mg once a day before meals along with Domperidone
30mg will have added benefits.
Eat light meals prepared under hygienic conditions.
Also take care of your hydration.
I hope this is helpful to you.
