Looks like I have to - I had a sleep study done last night (how they expect you to sleep when they wire you up like a Christmas tree is a mystery, but anyway...) and it showed that I do stop breathing sometimes - at one point my O2 levels dropped to around 85%, a significant number.
So now the question is what to do. There is a machine that you can use at night, but I want to avoid that. Losing weight will help, but there is also a surgical procedure that can replace the machine. I am looking into that. Will keep you posted.
