I was on omeprazole for probably 5 years, then was switched, Nexium, and Protonix, and have taken PPIs for probably 17 years, and haven't experienced that at all. Sorry to hear you're having the problem.
I can say that during that time I had one eye migrane episode that lasted a few minutes and disappeared, leaving me with a headache. That was the only time, though. I don't think it had anything to do with the medication. I wonder if another PPI would be worth a try.
Good luck figuring it out!
