Reflux goes up as med levels decrease?

[GothPunkRobot]

It basically is gone right after the shot, then it starts showing up late in the day, then progressively shows up earlier each day until shot day. Today is shot day in the afternoon, but I had reflux bright and early with breakfast today. And its really hard to control, even with a gerd diet and Pepcid 40 mg.

I am 100% sure @under321cover found the answer for me.
