Does CPAP Machine Help with GERD and Sleep Apnea?

I have GERD and Eosinophlic Esophagitis. I also habe always had unexplainable (as of yet) trouble sleeping. It was mentioned to me recently that sleep apnea is pretty commonly comorbid with GERD, and the possibility of me having sleep apnea is pretty high. My question is, if you are a person with both GERD/EOE/etc and sleep apnea, and you use a CPAP machine at night, how big of difference does it make for you? does it improve your quality of sleep? Does it ease symptoms of GERD etc.? Is it big enough of a difference to justify trying to get in to see a sleep specialist? For context, my town has a huge shortage of sleep specialists, so securing an appointment is difficult and a long process, so I don't necessarily want to go through the whole process if it won't make that much of a difference
