GERD
"Best medicine ever! I have taken Protonix for over 5 years now with no complaints other than when I run out and have to use over the counter meds that do not work. I usually take the Protonix 1st thing in the morning. It lasts all day. There have been times  I have forgotten to take it 1st thing in the morning however, no matter when I take it the pill still works within 15 minutes of being taken as if I had taken it in the morning."
