You're fine: You may have aspirated a bit, but it sounds like you cleared it immediately and all is well. If that is a chronic problem, you should seek attention from your doctor. Also try to increase the fiber in your diet. Eating a pound of vegetables each day and a cup of beans per day is linked to life extension but is also linked to less gerd symptoms.
