I bought these Orange Burps to combat my persistent acid reflux that keeps me from being able to lie dow to sleep. I liked the explanation of how these little pills work. Believe it or not, the night I took my first Orange Burp I had no reflux! I continued for the suggested 20 days and found I no longer had to try to sleep in our recliner or hurt my neck by using lots of pillows. I can't say enough about these! And when I do burp. The orange taste is subtle and pleasant, so much better than stomach acid!! I returned to the website right away to begin a subscription. I do not want to be without, but actually, after awhile I found they help even when I don't take them every night! I'm as surprised and delighted that a product works as advertised!
