insomnia
"Took Rozerem last night for the first time and got drowsy and fell asleep, but my body twitched all night.  My sleep was not consistent and I woke up all throughout the night.  In the morning I slept well past 11 a.m., I felt like a ton of bricks and could not get up.  I am usually up and about and running around all day long.  Today, I couldn't even leave the house I was so lethargic from the medicine.  I stayed home, didn't even change clothes, and laid on the couch with my eyes closed for hours.  It's almost 9pm the next day and I still feel really weird and tired.  My mind was in a daze all day as if I couldn't get anything done as a result.
