I am glad you don't snore...........that would keep me awake......lol. :)
Have you ever talked to your doctor about sleep apnea? Sleep apnea is the temporary cessation of breathing during sleep. Typically, the sufferer will awake gasping for breath. Sleep apnea may occur repeatedly, resulting in a poor night’s sleep and daytime drowsiness.
You may want to ask your physician about this as there are ways to dx it.
Take care and keep posting. Hope your day is peaceful.
