Hi Abbygal
I've been on Nexium for 2 months. I felt a little "funny" in my stomach area the first day or two but that quickly passed. I am on one 40 mg tablet per day, and can take two, if needed. I find if I take a second one, my eyes become really dry, irritated and red so I try to limit myself to just the one per day. Nexium has helped me quite a bit with the burning feeling, the burping, and the acid taste I was experiencing a few months ago. I'd say I feel 80% better. I am also being more careful with what I eat so that probably has helped as well.
