"I do not think I could fall asleep at a sleep lab"
That was what I thought too - but actually it was very easy. They
hooked up 21 different wires/monitoring devices to me and they kept a watch on
me during the sleep (one way glass) - much, much more information than any home
test can provide. As discrepancies arise the monitor "monitor"
can enter notes of what's going on into the computer at the exact time it is
happening.
My primary care doctor told me that I didn't "...have sleep apnea
because you are not fat." How wrong he was and I was sent by another
doctor to a sleep specialist. Heavy people are more prone to apnea, but
others can get it as well. After being diagnosed with apnea I was sent to
the sleep lab again to get fitted for a CPAP mask. So the diagnosis and
solution required two visits. That was two years ago and I've been through
about six masks before finding one that works and that's the ongoing battle for
me. Many have difficulties with the masks as well and give up at that
point.
