"i used rozerem and was very happy. it is strongly thought that nerve endings in the brain have been damaged by a virus or bacteria. i used it on a need to basis.  3 nights in a row, off a week, then 2 nights on and so on.  i used only 8 in a month and did sleep when i used it.  whether i felt drowsy or got a headache from rozerem i cannot say as my other diseases give me these symptoms, but i have to say i felt much better. i could not afford rozerem as my insurance would not cover it. i can now afford and will use 8 -10 a month with doctor&#039;s approval."
