I have horrible sleep problems. Actually, I should say, I have horrible staying awake problems. It doesn't matter if I sleep 3-4 hours or 11-12 hours, I am tired ALL the time to the point that I fall asleep while driving, at work, reading, watching tv - everything. I have severe sleep apnea, and I use a CPAP machine at night, and it either doesn't help, or there's something else wrong with me. I'm the most tired person I've ever met.
On days that I work, I generally get 3-6 hours of sleep, but on days I don't work, if no one wakes me up, I can go to bed at 1am and sleep until 3pm or later the next day. I hate it and I feel like I am missing out on a lot of time.
It's very difficult for me to wake up. I set 8-10 alarms on my iPhone to go off at intervals, and I fall back asleep between every one, and often I set more because I just can't wake up.
I hate it.
