GERD
"I started taking Prilosec over 6 years ago. It was very effective at helping with the acid and GERD symptoms, however my Doctor prescribed two tablets a day (Over recommended dosage-due to seriousness of Gerd). I seem to be fine until I started getting horrible spasms in my sides and intestines. I broke my ankle in March and the spasms were bad and the spasms worsened. I had my calcium checked and I was dangerously low. We backed down to 1 Prilosec and the spasms disappeared. So watch your calcium with higher doses."
