Well I too am having "weird" symptoms. It may be due to Omeprazole but not sure at this point. I switched from Prilosec OTC to Omeprazole which I thought to be the exact same thing. A couple months after the switch I am having chest tightness. Not really pain but just a weird feeling in my chest that almost feels like anxiety or stress and kind of a general weird feeling. Also kind of feels like a chest cold without the mucus that goes along with it. Went to the doc and had a EKG which was normal. I'm 30 years old and don't have any family history of heart issues. I'm going to stop taking it for a few days to see if the symptoms get better. I'll post back in a week or so.
