"doctor prescribed 50 mg for insomnia (with anxiety).  she said i could increase the dosage if necessary.  i have tried the prescribed dosage four times.  three of the four times i had nightmares to the point of screaming aloud.  one time, my husband could not wake me up.  the next mornings i do not feel good; i do not feel rested.  i am not going to use this rx anymore but asking the doctor for an alternative."
