I Have GERD And Have Been Taking Prilosec For Years.

I have GERD and have been taking Prilosec for years. Recently, I heard on the news that that taking Prilosec is not good for you anymore. My doctor told me to try taking it only as needed, but if I don't take it in the morning, I get extremely nauseous by mid-morning. After taking it I feel better and can eat with no difficulties. Is there really issues taking Prilosec and if so, is there something else I can use?
