The Bottom Line
A small warm drink before bed can be comforting, and some ingredients such as ginger may help certain digestive symptoms.
But there is no single glass that can cleanse your digestive system, cure bloating, or fix reflux overnight.
For most people, the best approach is simpler: stay hydrated during the day, avoid oversized late meals, identify personal trigger foods, and maintain healthy eating habits.
If digestive symptoms are persistent or worsening, finding the actual cause is far more important than relying on a viral bedtime remedy.
