I'm not agreeing or disagreeing with anyone here (been gone anyways for a few days). Just want to throw some data into the mix:
We don't really know what Schizophrenia is, folks. We have a bunch of possible symptoms as described in the DSM, but we are not certain of many things about it, particularly causal factors. We have only theories, as well as theoretical solutions. Pharmacological treatments sometimes work, and sometimes don't; and in neither case are these treatments without consequence. Generally what occurs is that the person is displaying abnormal (and usually maladaptive) behaviors that don't quite fit any other category in the DSM; so they get labeled as a schizophrenic. Sometimes this is "correct," and sometimes it is not.
The thing is, it is hard to know if it is a correct diagnosis when we really don't know what the diagnosis really is. Again, no real understanding of causal factors; just a series of possible symptoms coupled with inconclusive theories. Well, because of this, people get misdiagnosed all of the time (although how often exactly is not certain or conclusive either):

Furthermore, it gets even trickier when drugs enter the mix. How do you treat people with something that is supposed to be a somewhat empirical method (medication) when your diagnosis and understanding of the illness is about as ambigious as you can get in the medical community? What you end up with, sometimes, is the treatments being more damaging then the "illness." For example, Neuroleptic drugs are generally given to schizophrenic or psychotic patients; but one of the side effects is TD which is a disfiguring disorder of the central nervous system resulting in a variety of involuntary movements, particularly of the tongue, lips, and jaw. muscle movements. This would of course make a "schizophrenic" person seem even more so, wouldn't you think?
There are many problems with the pharmacological approach that I don't even have the time to get into. The argument is quite far reaching among MD's and Psych PHd's; so there is know way that we'll crack it on an internet forum.
On the other hand, though, a major problem with schizophrenic patients is that most (over 1/2) are not actually aware of their own illness. This further complicates things.
Anyway, I can go on and on, but the basic conclusion is this: 1. Medication is not without side effects, is not always the answer, and therefore should be used only as a last resort. And 2. If you have been diagnosed with schizophrenia or some other serious mental illness, DO NOT try to treat this or diagnose yourself, or do ANYTHING on your own - always involve your doctor. If an entire medical field does not have all the answers regarding your illness, then you aren't going to find those answers on your own. Work with your professionals. And, your doctor should be someone who doesn't try to pretend to know all the answers, but who does want to find what will work for you to get you the help you need.
Anyway, I have no idea what else to say on the matter...
