There seems to be a lack of stomach medicines out there and this one seems to do the trick. I hate the taste of this product and for that reason alone I will not give it a ten. I feel like I'm gagging as I swallow it and it's worse because it coats your throat as it goes down. The taste is chalky and pepperminty. I don't even know how to explain it. It's gross! On the other hand I have to say that it does work to settle stomach problems and it does calm that area down. I will take it for that reason. Recently I switched to the pepto bismol chewable tablets and those aren't the best tasting either, but the taste doesn't stay in your mouth like the liquid and I like them much better. Some people don't mind the pepto bismol taste. I'm just not a fan at all. Effectiveness It is effective in making an upset stomach feel better. It does work for that. Ease of Use It is pretty easy to use. You just pour, measure and drink. Immediacy It works pretty quickly and that part I like.
