What would I do without ENO?!?! The burning and pressure stays in the pit of my stomach and is relentless. After a few minutes of using it, I can feel the burning feeling fade away and in 10-15 minutes, I'm back to myself. Fastest and most effective dyspepsia solution I have ever tried. A bottle typically lasts a long time as only a little is needed and the effects last for hours.
Have used this product ever since I was a child. Over 40 years. It is effective and easy to use. Highly recommend.
Works super fast and well. Reasonably priced compared to other places.
I was surprised that it tastes this good. And it's Eno. You can't do better than that.
I'm from the Bahamas, and used this when I was a little boy. I'm 48 now and it still beats out all the top name brands. ENO has always instantly fix indigestion and gas issues.
This product is great for digestive disorders. Heartburn gone a few minutes after drinking this. One spoonful in a glass of water does it.
