"Took this a year ago for about 3 months, and seemed to work for the most part.  Just had a little bit of stomach 'pain' due to the PPI's being blocked.  Went off after that duration and had few issues.  Later, I was on it for two weeks and it gave me strange side effects like lower abdominal aches in the back, a 'butterfly in the stomach' sensation that would not go away to the point where I would get 'attacks'.  In the future, I'll only use this medicine for a week or so in case I really need it."
