                        I have been using prevacid for three   years now and it is under control. I   also take acidophilos (sp?),which has   helped even more. The worst side   affect from taking prilosec, propulcid,  or tagamet, is severe short term memory   loss. Prevacid (lansoprazole) has the   least side effects. But it is also the   most expensive. If you are having memory   problems this might be the cause.    Good Luck   Thomas:-)
