"I have used Prevacid 30mg (lansoprazole) for almost a year now. It works wonders for my acid reflux, except when I'm bad and eat something to trigger it!  I have found it works better when not used daily.  My Doctor said do not take it every day as the effects will wear off sooner, take it when you need it or on a day you know you will be eating something to trigger your acid reflux.  As any other medication the effects of relief will wear off but, when you stagger, you take it. It works all the time."
