I suffer from mild sleep apnea, and hypothyroidism. I currently take medication
for the thyroid issue. A few years back and before taking the thyroid medication, I had my first episode while driving on the highway. I felt severe dizziness combined with nausea, clammy hands, and a sensation of
ing out. I noticed that when I would lower my speed, the sensation would subside a bit, but when I would try to accelerate to a speed of
65 mph, the sensation would come back.
