As others have already explained, you can now do an in-home study. Not nearly as good as when you're all wired up in the sleep center. But still good enough to get a general indication of how you are doing.

Okay, you still resist that, so ...

How about going to bed, for one night, with a small, inexpensive, device on your finger? Viz. a pulse oximeter. Surely you can handle that for one night???!!!

When you stop breathing, which you admit you do (at least according to your wife), the amount of oxygen in your blood drops. Perhaps to unsafe levels. This is very bad for you long term. Very bad.

So, just try the pulse oximeter. For a few nights. It's cheap and non-intrusive.

In anticipation of scaring yourself into getting a CPAP machine, buy an oximeter that's compatible with SleepyHead. Here's a disussion about that: http://www.apneaboard.com/forums/Thread-What-oximeter-works-...
