Are you refering to the 24hr ph monitoring test?
If so, I had it done and what the surgeon told me was that the test showed that I had reflux, but not enough to warrant surgery and to continue with the medication.
All the doctors I have seen tell me to take the medication once a day in the morning. I take it immediately when I get up and then wait 30mins before I have breakfast. Sometimes I also take reglan or domperidone and those I take just before I eat.
My experience with this is that you quickly remember to take the medication because without it the symptoms return. That is enough to remind me!
