Overdose - Cant even stand up ?!

[c17h21no4]

swim's really really sorry if he posted in the wrong section but he took 250mg amphetamine and after that another 500mg and when he tried to go to the bathroom he just tripped over something ( there was nothing there ). swim usually takes a dose and when he feels that he is coming up hit's another one and usually starts to eat an ice-cream or chocolate. he says he gets the best high ...
swim knows kind of everything about ampin' and he knows how it affects the cerebellum but that didn't till now ... and this never happened. this wasn't swim's highest dose by far ... he usually does meth , but since p2p is kind of unavailable to swim and nitroethane he thought to do it just cuz' it's rare. now swim did another dose to see it that feeling comes back ... only 250 mg.
should swim get like serious and do a couple of tests ? is this something that for example an experienced tweaker should reduce his dosage at least for a few days ?

well. since no one replied and since swim told me he's better ... not that he felt sick or something , he felt great but he had no coordination , ballance or strenght. the funny thing is his pulse was 87 , had frozed hands ... well the hands are really common
i'd like to note that it was pure , and swim was 100% that the reaction was perfect he even tested it.
what can you say ? stranger things have happened
