It sounds uncomfortable to have throat pain, difficulty swallowing, and acidity after drinking excessively. These symptoms may be due to irritation of your throat and acid reflux caused by alcohol.

• To ease acidity and protect your stomach, you might consider a medication like Omez-DSR Capsule, which combines omeprazole (a proton pump inhibitor that reduces stomach acid) and domperidone (which helps stomach motility). However, this should only be taken after consulting a gastroenterologist or your primary care doctor.
• Meanwhile, avoid alcohol, spicy or acidic foods, and eat smaller, bland meals like khichdi or curd rice to soothe your stomach.
• Drink plenty of water and avoid lying down immediately after eating to reduce acid reflux.
• If your throat pain worsens, swallowing becomes very difficult, or you develop fever or breathing problems, seek urgent medical attention.
