Hi - I am new to this site and have had the symptoms that you described here for around 3 years now -- indeed, veryfrustrating. I have had stomach issues as well, for some time now. How long and at what dosage did you have to take the Zantac to see a difference? Thanks so much for your help -- as well all know, this is a terrible problem to have - especially because it's hard to talk about and have people give you honest answers, so thanks SO much for your help!!!!
