My son was taking this medication for about a month and had horrible headaches after taking it. Felt like he was in a fog and vision problems, couldn't concentrate, had to quit driving and going to work. After many visits to the emergency room and many doctors. we found it had burned his stomach. Now he is on Nexium and it is amazing the difference. His headaches are maybe 80% gone. It seems that this medication is bad on the GI track. He took it with food but it just is hard on the body. If your symptoms stay have an endoscopy to see if it has done any harm to your GI track.
