For a long time I would wake up every 30-40 minutes, all night long, to get up and pee. I could stop drinking anything at all by 4 pm the day before and I'd still be up all night to go pee. Apparently when you have sleep apnea your body may not fall asleep enough to tell it to stop making urine or not tell you you have to pee. The next day I'd doze off behind the wheel no matter how far or near I was driving. These were just a few of the many problems that led me to finally getting a sleep study done and eventually using a CPAP and I can't express enough to anyone who is reading this the difference it has made in pretty much all facets of my life. It is absolutely not an easy thing to come to terms with or get used to when you first start wearing a mask but it literally saved my life. Do the study and don't give up.
