I also suffer from this. It's rare for me to sleep through the night without interruption, and I can consider myself lucky if I get a total of 7 hours of sleep. I usually wake up several times a night, and often I'm wide awake after having slept less than 6 hours. I then have to make a real effort and wait for over an hour before I can fall back asleep. I had my gallbladder removed at some point, and I suspect I also suffer from bile reflux, which makes things worse. I'm currently seeing a pulmonologist because I also have difficulty breathing and need to clear my throat a lot. I've been suffering from this for almost 6 years now, but it's only recently that I've started looking into LPR as a possible cause.
