Gastritis problems

Hi according to the health authority gastritis is easy enough to sort out.  You just need a PPI tablet and something like Gaviscon to coat the stomach.  However I have had gastritis for two years plus since my gallbladder was removed.  Its not getting any better despite taking two PPIs a day and Gaviscon.  In fact it now flairs up and is more painful and Im in agony.  I can't sleep with it and now have to take Tramodol to try to get to sleep.  I wonder will it ever get better?  I can't go on like this,its so painful and persistant.  Has anyone else been through this?  Thanks for any ideas.
