Love this as it helps me so much.

These are a lifesaver for me when I get these chronic stomach issues I deal with. I go through phases where i suddenly get super sick and nauseous and even the tiniest gas bubbles feel like knives. I can't take prescription anti nausea meds as I get a seriously diverse reaction. These in like 10-20 mins will help me not have to curl up in a ball and cry. I have Chrons and IBS and more. So stomach issues are my constant struggle. I keep these in my purse and even on my car if one of these “attacks” start. It's like a quick fix that allows me to try to relax and are able to sleep through it. Thank goodness for Alka Seltzer extra strength!

The Un-Burn

I absolutely love this product. It works right away on my acid reflux %26 heartburn. It's so easy to make %26 doesn't take much. It doesn't taste great, but if I can handle it, then anyone can handle it. If it's that terrible, just breathe through your mouth after. Try it. Feel the UN-BURN. You'll feel so much better. 😉

Excellent relief for heartburn

This is excellent if you have heartburn. It is my go to and it works every time. I use the one that you drop in the water. I know there are chewables, but this is something that I know that works so I will continue and I would highly recommend anyone who suffers from heartburn to try this.
