I have been taking Nexium for at least five years & prior to that it was Pariat & prior to that it was Zantac.Over all, I have been taking these types of drugs for at least twenty years.Whenever I try to stop the symptoms come back. Are these drugs causing any long term damage? I am also taking Ezetrol,Crestor,Bicor ,Karvea & Cartia. Thanks, Cam
