Out of curiosity, do you drink alcohol? And if so, does your p-doc know this? My former p-doc refused to prescribe me any benzodiazepenes (to take as needed) for my anxiety because of the fact that I do drink alcohol regularly, even though I told her I wouldn't mix the two. (I eventually got her to prescribe me like 8 of the smallest dose of Ativan and haven't even used them.) I know you're not specifically looking for those, but I think some sleeping pills aren't safe with alcohol either, so that's a possible reason for the p-doc's refusal to prescribe them. I think they worry about liability/lawsuits.

I agree that you could ask about trazodone or Gabapentin. I also briefly took Trileptal (for bipolar II), but it made me incredibly sleepy (same with Gabapentin--haven't tried Trazodone). So maybe a small dose of something like that would help? And it wouldn't be a technical "sleeping pill."
