I have insomnia from my pain meds, sometimes I'll be up for 3 days straight. I have found that almost any benzodiazapine will work, some docs do not like to prescribe diazapam b/c they say it is more addictive. Funny my doc will give me as much zanax as I need but will not prescribe ambien or diazapam. hacion works, some docs try to use seizure meds for sleep b/c of their side effects but I think that it isn't worth it b/c of all of the other side effects.
