Suggest Medication For Heartburn And Panic Attack. I Had Gastric Bypass Surgery.

I was recently started on clopidogrel and taken off aspirin but I also was taking omeprazole and now am suppose to switch to Prevacid. But I had gastric bypass 10 months ago but what I read says that I should take neither gerd medicine because they can affect the clopidogrel. Butt now I seem to have heartburn and had a panic attack. I also had bilateral pe s after sx and later on in January. I Had a Tia. Any thoughts for me. I seem not to feel like these meds are working together as they should. I was on Coumadin therapy for 6 mths after the pe s. And then after te Tia Asa 81 then Asa 325 then switched to the clopidogrel. I had no residual from the Tia but I always seem anxious now
