Since I started on the Zelnorm study last week I havn't been able to take any meds whatsoever, not even antacids or sleeping pills.I dont actauly get the Zelnorm until Sept-4,I have to do a phone survey you know ( have you had a bowel movement if yes press 1.)I have to do this so they can have a before and after.Any way can anyone help me with natural remedy to help heartburn, nausea or even sleeping, any thoughts would be appreciated.Marvin
