Hello, croft hope everything is going better now! I started taking nexium about 11/2 weeks ago and I have good and bad things to say with it. The good part is, it has helped my gastritis a lot and barely gave had any flare ups since I started, the bad part is, like you were having with omeprasole, I'm getting a jitters, nervousness, slight dizziness and fuzzy feeling in head. I don't know whether to keep taking and deal with side effects or stop taking. I'm confused cause my stomach is pretty good and I'm afraid if I stop taking it, I'll get burning again but these side effects aren't pleasant either!
