I just (i.e. 30 minutes ago) dosed my first real Tramadol (prior was one bout with extended release tabs that didn't do anything) . It was something I'd never really been interested in, seemed like the poor man's opiate.
I combined it with some codeine, to round off the high (I love codeine), and diazepam, to reduce the propensity of seizures,
300mg, and wow. Not only do I feel quite lovely; warm, comfy, cosy, etc (I could probably lie down and nod out right now), I find the mental effects amazing.
I don't really suffer from depression (no more than your average joe with the problems life throws at us), but more importantly, I feel confident and supremely just, well, on top of the world! Internal elation.
I was just on the phone to someone very important, business-related, and I absolutely dominated the phone call. It was easy, the words came straight to me, and I was charming, smooth tongued and polite (even moreso than usual

)
So, I can imagine that for those who have depression, it would work wonders. For a week. Until you build up tolerance, lose the anti-depressant qualities, and end up having a seizure because you've upped your dose way too high to counter the aforementioned effects.
