this tablet is used occasionally when the stomach has too much time stress and heartburn occurs. It seems to just that one time a coffee cake or drinks too much or eats here and there. Too little sleep the stomach upsets. I've noticed that it acts best when it takes up the day before the evening. Acute has less helped it. I recommend still prefer to eat healthy and less help out with these tablets. It also has some side effects, which will of course be different for each person. So I'm clear, when I occasionally engaging this. Effect 5 stars
