yo, not sure what trozodone is but i assume you mean trazadone.
i was once prescribed these for sleeping and can assure you that the recreational potential with these is rather meager. i believe it is a phenyl group which is then bound to a piperazine ring although i stand to be corrected and is used as an anti-depressant usually, and in low doses for anxiety disorders and insomnia. i've heard that some people have had a relatively good experience on these and has made them hallucinate.
i believe that this crap turns into mCPP in the body too. its essentially a prescribed piperazine of which i have no idea WHAT this could be used for effectively.
personally when i took 150mg of the stuff i had some extremely strange visuals, was extremely drowsy and this lasted for about a day afterwards too. had some real fucked up dreams too. like real fucked up. scared me shitless for weeks after and when thinking about them now im getting scared. the fucking headache too...... that eternal pounding........ i thought i was dying. damn that stuff is horrible.
imo throw them away.
not sure if anyone else has any exp with them. but i threw them all out after my experience. wasn't pleasant and i hated every second of it, not to mention i couldnt even stay awake.
oh and did i mention i couldnt take a piss and when i finally did it was brown? dont even get me started on the fucking agony i was in with my bladder.
and dont forget taking a shit either! i was just as bunged up as if i'd drowned myself in opiates.
fuck it was awful.
