How much Omeprazole are you taking and for how long have you been taking it? Did you try antacids before taking Omeprazole? I take 20mg Omeprazole for gastritis/esophagitis and have some similar symptoms to you. I may stop taking it to see if any symptoms improve. I really think you need to see a neurologist if you haven’t already to get a brain MRI. You should get to the bottom of your low blood pressure which made you pass out. It could be neurological and/or cardiovascular.
