Hypercontractile Esophagus, aka Nutcracker or Jackhammer Esophagus

I have recently had manometry and impedance tests done, and received a diagnosis of hypercontractile esophagus and NOT diagnosed with GERD, which is what I assumed was causing my problems these past few years. The doctor prescribed an old drug called HYOSCYAMINE that has a long list of concerning side effects. Has anyone taken this particular drug and, if so, was it worth the risks of the medication to resolve your symptoms? He has two others on the list if this one doesn't work, including VIAGRA as his third choice - haha! It seems counterintuitive, but who knows?

As a bit of history, I do not appear to have symptoms with this condition that are as significant as they are for others, though I do count it as the disease that has the greatest impact on the quality of my life. A chronic cough is the symptom that impacts me the most - I often have to get up in the middle of the night to drink a cup of coffee for an hour before going back to bed - caffeine is a mild bronchodilator that works well for me. There have been nights when my pulse oximeter showed that my O2 levels dropped as low as 85% from the coughing. I have to do deep breathing exercises to get the oxygen back up again. When that happened for a straight week, my doctor put me on a Wixela inhaler (after she scolded me for not calling 9-1-1), which resolved the cough entirely for several months. Alas, that isn't an appropriate long-term solution for this condition.

I can no longer drink my beloved daily glass of red wine, and consuming high fat foods is a recipe for nocturnal vomiting (why does everything bad have to happen when I want to be sleeping)? I often have a sensation of a knot in the center of my chest (globus), but no heartburn or severe chest pain like others get with this condition. Occasionally, I have the sensation that food or capsules haven't made it all the way down, but I can usually resolve it by drinking a glass of water while keeping my chin low (this apparently straightens out the esophagus).

I would love to hear from others about their experiences with this condition - I learn the more from this community than I ever have from my doctors!
