"i had been having horrible anxiety and couldn&#039;t sleep. i would sleep for an hour and my brain would race with a to-do list. since i already was on medication for depression my dr prescribed trazodone. the first day was hell. woke up several time during the night, head pounded the next day, and i was on a fog all day. i wanted to stop but tried it again after talking to my dr. i slept better the second night but still woke up with a headache. i didn&#039;t have the fog the next day. by the third day i was fine. sleeping like a normal person and able to function during the day. found out i was getting the headache and the foggy feeling because i was not allowing myself enough time to sleep."
