I am waking up about every hour at night. I do have BPH, but much of the time I have only a little urine. This has been getting worse and now when I try to nap during the day, sometimes I wake up after only 30 minutes. I do not believe I have sleep apnea, but am scheduled for a sleep study. Could some level of heartburn, which I sometimes have, but does not seem to be serious be a major factor, and what is the best way for me to proceed?
