Dear Hearts; I have chronic sinitus-with the meds I'm on,if I DON'T drink 1-2 gallons of water a day,I get heart palpatations.But that post made me think:I still find it VERY difficult to believe that too much water is the cause of IBS symptoms in anyone.Drinking too much water,to my knowledge as a biochemistry major,is only a problem when consumed faster then the kidneys can process it.Data to the contrary has not been consistently produced in the lab to date to my knowledge.Anyone want to add anything to this? Sincerely, Andrew L.
