Wow that is unacceptable for the physician and I sympathize. I have had bad experiences like that, except with pain medication instead.
For sleep, I have found two supplements to be very effective, as well as antidepressants in general but you would need a prescription. The first supplement I use is 2.5mg melatonin every night, no more than 5mg. The other is magnesium glycinate, 400mg, and I swear by this supplement, it helps me fall asleep and if I have to get up for some reason I fall right back asleep.
Have you thought about trying these? They really changed my sleep completely.
