Two days does indeed seem a bit quick to be trying anti-psychotics, particularly considering some of their ensuing side effects... Still, I've read that sometimes psychiatrists will not be sure of a definite diagnosis but will still prescribe specific meds, but only as a process of elimination. Sort of like a trial and error protocol if that makes sense, in order to better ascertain what you might be suffering from.

All this mainly because diagnosis is such a subjective construct and hard to quantify (e.g. many psychological disorders share similar symptoms).

But do question your psychiatrist(s) esp. as you had bad reactions to the meds in question & have them explain what they are doing and/or how they propose to diagnose and treat you. It is very important that you know the 'why' of whatever they give you, so you are a full partner in your diagnosis & subsequent treatment.
