I find that extreme paranoia and anxiety even borderline hallucinations can develop very quickly (over just a few hours of use, not days) even with doses that are not crazy. Unlike meth and other amphetamines which seem to take days to develop the extreme paranoia, anxiety and hallucinations that can be induced by PV in a matter of hours. Obviously with almost any stimulant some mild anxiety and even very mild paranoia can come at even small threshold doses, I am not talking about this I am talking about illogical level stuff.
I would just say to take it slow, know your dose and try to limit yourself to short sessions. Also keep a benzo on hand to help come down or if things get too intense.
I am wondering how much you did OP and for how long? Are you unsure what drug you actually ingested?
Either way, if you did Methamp (crystal meth, Ice), amphetamine (Adderal, Dexadrine, amphetime satls), MDPV or any other of the stimulants out there that are used recreationally you should have got some enjoyable or euphoric effects from it.
If you did get some pleasurable effects but the negative effects over powered the positive, I would guess you just did way too much the first time.
If all you got were the negative effects I would guess you actually did too little (This happens to me with all three mentioned. I do too little and all I get some agitation and anxiety with out any euphoria).
What you got could have also been something that causes all of the negative effects with out any euphoria or something like l-amphetamine (maybe???) as this is what causes many of the negative effects associated with Adderal compared to Dexadrine.
