hi, basically when you stop taking nexium, it takes a few days to build up enough acid in the stomach to make you really feel it, and ofcourse when you get back on it, it takes just as long to neutralise it and block it, so be patient,
i should know ive been on
nexium for seven years and every now and then i give it a break for about a week, and what happened to you happens to me every time, cheers.
