and looked through the old Zelnorm posts and didn't find anything on side effects and/or vertigo/hallucinations... I experienced what I can only describe as mild hallucinations and moderate to severe dizziness last Friday/Saturday... and swear I was seeing things, too (purple ribbions flying in the trees...)I am NOT KIDDING and am VERY serious. I don't know what was going on! Could it be the Zelnorm?Anyone have any ideas????
