The tap water felt more frothy/bubbly in my mouth than the RO water I have solely drunk for many months. After drinking about 1/6th of a gallon I noticed a burning feeling similar to slight heartburn near the bottom of my esophagus or in my stomach. It didn't last long, under a minute. I have drunk tap water once before, deviating from only drinking RO water, and I had the same symptom. Has anybody else experienced this?
