Hey guys. I am having a sleep study next month so I will know soon enough, but I want to know if anyone else has/ has heard of sleep apnea with no daytime tiredness but very strong other symptoms. I have been having really bad concentration issues, feeling almost intoxicated at times. I don’t really feel recharged when I wake up, but not excessively tired. It’s just different, from everything I have read you either have no symptoms or you can have many, but all cases I’ve heard of include excessive sleepiness. Any input would be appreciated. Thanks!
