Something to think about.
what I do with this product isn't for everyone. I suffer with a lot of pain and fatigue. I take a pure kick or a c 4. Drink mix. Mix then in a tall glass of ice water and my pain and fatigue are lowered enough, I can get up and do what I need to do. The cost is high, butits worth it for me.

I always have to have this in hand. I ran out and needed it. You always need it when you don’t have it so anyways they ordered it again works fantastic. I swear it Alka-Seltzer this way or Alka-Seltzer for colds or anything. It’s always been my go to.

Awesome product
This works so much better for my acid reflux / GERD than the actual prescription my doctor has prescribed me. I've also tried Cool Pepto and many other products, but Alka-Seltzer Extra strength never lets me down. I even brought the Alka-Seltzer Gold since that one says specifically for heartburn and bloating, plus it has less sodium (salt) than the Extra Strength one here, but the Gold doesn't actually knock it out like this does. I've used this product for many, many years, decades even and nothing compares. This is a life saver so to speak
