GERD
"If you don&#039;t get ahead of an attack, this pill won&#039;t work. I have been on it for years now and have had little problem with it until it didn&#039;t work one weekend so I doubled up on it and ended up in the hospital a week later with seizure due to hypomagnesia (or however you say lack of magnesium). Make sure you are getting all your electrolytes when taking proton pump inhibitors."
