My husband snore. He can fall asleep any time of the day if he is laying down or even sitting, quietly. I can't. I do usually sleep fine at night, but only at night, and in part because I take a good dose of Seroquel XR. On the very very rare occasion I have fallen asleep during the day, I woke up totally discombobulated, thinking I'd slept 24 hours straight, when I only slept 30 mins max.
