doc switched me from Nexium to Prevacid

ok, I give!!!!! I tried to get off Nexium, I was ok for a couple of days but BOOOMMM I was up all night soooo nauseaded. I went to the doc this am and told him that the nexium was helping a little but that I was having side effects so he gave me some prevacid, so I popped one asap and within about an hour I felt fine.

Is prevacid that much different from Nexium, I don't know a lot about these meds. It seems to be working like a charm. Are there any side effects from the Prevacid I should know about?

thanks!
