I had a few times on Nexium where it felt like heartburn. When I changed to Prilosec, I felt like I didn't have any symptoms so I just slowly stopped taking it every day. I wish now that I would have kept taking "something". The ENT doc said that 50% of patients don't have any heartburn, sore taste, etc. I just started Prevacid because my mother takes it. I'm not sure which is better, Nexium or Prevacid. What do you think?
