I can have what I think is a great night's sleep but wake up with brain fog, irritability, fatigue, low mood, etc. All I can do is lay in bed in the dark on these days. The next night I will get the same sleep but wake up energized, clear headed and positive. This happens often and it is so frustrating. I have sleep apnea and have been on cpap but it hasn't helped. Could this be medication related? Brain chemical related? Or sleep related like narcolepsy? Has anybody else had experience with sleep and mood? Especially such a major swing in mood from one day to the next with just one night inbetween?
