I&#x27;ve done some sleep studies too, and had the opposite experience. I was suffering from sleep apnea, which makes it impossible to sleep well. The electrodes during the sleep study were weird, but for much of the night (especially after the first night of study) they were running a CPAP at various levels to determine what I needed to keep my airways open. I slept better than I had in months.<p>I&#x27;ve been using the CPAP ever since, and now I sleep very well most of the time. I fall asleep in just a few minutes (used to lie awake for hours) I sleep all night through, and I often wake up a few minutes before my alarm goes off.
