Hopefully someone there can give me advice on where I should look next. I have had this problem for years but the last year it's been worse. I can't wake up. I sleep the weekends away and even though I sleep 8-9 hours during the week, it's still extremely hard for me to wake up. It takes me hours to fully wake up. My head doesn't clear - I feel like I'm drunk and it's hard for me to concentrate. I also occasionally experience sleepiness when driving and have to pull over and sleep. I've seen a hand-full of doctors and been through a battery of test including blood, thyroid, and a 2-day sleep study. No one can figure out what's causing the problem. I'm currently on hormones to see if it's menapause related but that's not helping much either. I take Allegra and Astelin for allergies and wondered if it could be allergy related although this started long before I started taking allergy medication. I appreciate any suggestions!!
