(HealthDay News) -- Gastroesophageal reflux disease (GERD) is a gastrointestinal condition that often triggers uncomfortable nighttime heartburn that affects sleep.

The National Sleep Foundation lists these suggestions to help keep GERD under control so you can get a better night's sleep:

• Don't lie down after eating a big meal.
• Try to eat smaller meals instead of large ones; practice an upright but relaxed posture as you eat.
• Try to avoid onions, chocolate and high-fat foods, as well as alcohol.
• Don't take potassium supplements.
• Take medications while sitting in an upright position and swallow with a lot of water.
