If you're feeling headache it could be associated with your gastric problems. Your gastric problem would require an antacid and antiemetic(if required). I would advise the following lifestyle and habit changes: - Avoid/Reduce spicy, oily, fatty and fried food items - Avoid smoking and drinking - Avoid acidic drinks like coffee, garlic powder, chili powder, peppers and tomato products - Eat smaller, more frequent meals - Food items such as ginger tea and/or chamomile tea with honey, yoghurt, cranberry, apple, carrot juice, soy foods to name a few may give some relief. If the headache is persistent visit your nearest physician and get evaluated.
