This is usual to happen to people with having acid reflux
disease. You should take very light meals during night and you should take 2 hours before you go to bed. Use a thicker pillow and try to lie on the left side rather than lying straight. Do not drink even water before you to bed. Try taking proton pump
inhibitors (such as Esomeprazole/Pantoperazole) to reduce your acidity.
