Drugs and meds can be effective, but I found that they are so often hit and miss. They often don't work or have horrendous side effects. They are not that long lasting, and effects are often there only as long as you are on the medication. So while medication can be effective for some people, I don't think we are that advanced in out knowledge to really be able to treat mental illnesses that well with medication. I think it should either be the last resort after everything else has failed or taken in conjunction with therapy in order to make teh therapy more effective or ease the person into the therapy. I'm not really into meds just being given away for any mental disorder. I think that happens way too often. It is easy. It takes a lot less office time than therapy. Takes a lot less work on the part of the doctor...they just give out the script, take the money and see the person next month.
Medication, in nearly all cases of serious mental illness such as schizophrenia, bipolar disorder, and schizoaffective disorder, is absolutely necessary in order to counteract the faulty way in which the brain processes certain neurotransmitters, to put it as simply as possible. Therapy alone isn't enough. I have bipolar disorder and my medications work perfectly. It is not possible for someone with my condition to remain healthy without being on medications. It is a medical impossibility due to the manner in which symptoms cumulatively get worse every time a person lapses into mania. If bipolar disorder goes untreated long enough, it eventually becomes impossible for that person to "come back" to themselves, although in this day and age such cases of advanced chronic mania are not so common, but I have seen them before in person and it is certainly not pretty and quite uncomfortable to be around.
As for side effects, nearly all side effects from psychiatric medications go away after a few weeks or months. If the side effects from one medication or dose do not go away for some reason and are considered intolerable, a new medication or dose may be tried. In regards to medications being easy, this is certainly not the case at all. Often, many medications and different doses and combinations need to be tried until something that works is found. It took me around a decade to find something truly effective. The newer medications tend to have a rather high success rate overall and symptoms appear to be much more tolerable for clients. In addition to this, most of the newer medications do not cause the long-term side effects that are common in older psychiatric medications, such as tardive dyskinisea
As for schizophrenia, medication is the only effective treatment available. The same goes for schizoaffective disorder.
Of course, a combination of
both medication and therapy is necessary for the successful maintenance of most serious mental health issues. Medication alone isn't enough in any case, unless you are speaking of cyclothymia. Most persons with cyclothymia do not even need medications because the symptoms of cycling are so mild. Additionally, some cases of unipolar depression may not require the client to continue taking medications for the rest of his life.
In response to your comment concerning the fact that medications are not long-lasting unless a person continues to take them, that is precisely the point of taking medications; mental illness is a chronic condition which must be properly treated and maintained throughout the course of one's life. Diabetes is a good analogy. People with diabetes must take insulin and have their condition treated for the rest of their lives; it is necessary to do in order for the person to remain healthy. The same goes for mental illness.
Lastly, to address what you said about doctors having to take less time with medication, I believe that you may have a fundamental misunderstanding of what a psychiatrist's role is. Psychiatrists only prescribe medications; this is what they are trained to do. They do not dispense therapy. In addition to having a psychiatrist, it is necessary to obtain a licensed therapist trained in treating mental illness to provide therapy in addition to the medication regimen.
I certainly agree with your recommendation of CBT, but CBT alone is not an effective enough treatment alone for most mental health issues. The best treatment in nearly all cases of mental health issues involves medications in tandem with effective therapy that caters to the individual needs of the client. Please keep in mind that borderline personality disorder is an extremely serious mental health issue; it is a bit naive to assume that therapy alone would do enough. However, there have been many breakthroughs in therapy techniques that seem to be very effective in treating BPD. At this moment I cannot recall the names of the new techniques as my area of expertise is bipolar disorder, but there is much more available now for persons with BPD than CBT.
Of course, the OP and his girlfriend should discuss what they have read in this thread with a qualified mental health professional (not just someone certified who is posting as is my case) to determine what the best course of treatment should be.
