Chamomile tea brings a lot to the table when you drink it before your slumber. Drinking chamomile tea one to two hours before bed can help reduce stomach inflammation and balance out acid levels. As an added bonus, the tea will help you sleep better and can work as a relaxing agent. Tea has trace amounts of L-theanine, which can pass the blood-brain barrier to help relax your mind. When it comes to acid reflux, it’s good to reduce stress as much as possible. It’s important to note that natural L-theanine can also be bought as a supplement.
