I am prescribed ambien and trazadone for insomnia I only sleep for short periods of time? Now when I got the ambien I was told that it was the strongest sleep aid available - it was also a controlled substance. Now my trazadone isn't but i feel like ambien doesn't even come close to making me fall asleep. Now my doctor said to only take one when I told her one wasn't working she said that you can't take two at a time. Do you have any opinions on theses meds or what I've said?
