I've been on Dexilant (formally Kapidex) since it came out. I've found that everyone had a PPI that works better for them than others and that it differs from person to person for which one works best.
I had some major side effects with another popular PPI, but have found great success with the Dexilant. If you are going the PPI route, I'd recommend trying it. As with all PPI's you should give it about a month before deciding if it is going to work for you or not.
