Now, if you are feeling sleepy in the day also, it means your body is not getting relaxed and rejuvenated when you
sleep. This can happen if you fail to have enough deep
sleep.
Sleep apnea could prevent you from having enough deep sleep. And you do feel sleepy throughout the day. Contacting a sleep specialist for a sleep study will be a good first step. If you do not have a sleep specialist in your area, just find out where you can get the sleep study (polysomnography) done.
