Fortunately for me, my insomnia is only transient, and these are the meds I've tried:

+ Temazepam - absolutely useless for my case, I might as well have taken lollies. A psychiatric registrar gave some to me to tide me over a weekend and I shouldn't have bothered.

+ Dothep/dothiepin/dosulepin - I was naughty and borrowed some from a friend who swore by it for sleep issues [he also took it for migraines]. I took 50mg and it made me drowsy, but didn't knock me out as much as I'd expected. It's a TCA.
