@alleycatkate I want to share with you a few things from my journey with laryngoesophageal reflux. I was prescribed high dose PPI's when I was first diagnosed with reflux and MAC because of a chronic dry, especially early morning, cough, with lots of post nasal drip and throat clearing. The PPI's eventually helped a little with the cough, but getting a mechanical bed to achieve a 30 degree angle and going to bed with an empty stomach made the most difference. Then, after months, it was very difficult to wean off the PPI's! It took months. There can be a rebound increase in acid production, and it’s the only time I my life I’ve ever had heartburn!
In addition, everyone should know that the PPI's and things like Pepcid don’t decrease the volume or frequency of the reflux. They just reduce the level of acidity. There are other chemicals in the reflux that still harm lung tissue when they cross over into the wrong space. In fact, lowering the acidity is thought by some to actually increase the reflux activity, because the acid is a signal to the valve to close.
I’m sure there is individual variation, but it’s not a simple situation.
