When I have had GERD in the middle of the night (which as I laid out in a long post is now pretty much a thing of the past with dreadful detours thanks to PPIs)... I too found the acid invaded my lungs and caused asthma. I knew others with whom that was also the case. The trick is to heal the underlying GERDS. Believe me it can be done. It can NOT be done with PPIs which suppress acid production.

Eat much earlier. If you are overweight, get Jason Fung's Obesity Code and try intermittent fasting. It will heal a great many chronic diseases, including Insulin Resistance causing type 2 Diabetes ...get Fung's Diabetes Code for that.

Good luck on your healing journey. Most Western trained docs haven't a clue, still, despite all the double blind trials they run that end in failure for the received "wisdom."
