The only thing that concerns me about the idea of taking multiple medications is, are they serving a purpose that cannot be fulfilled more healthfully and less (potentially) harmfully in some other way? Psychopharmacology exists (presumably) to help people, and for some people it works very well. For others it does not. I am one of those people, and I am also on more than one med, and every single day I question whether or not they are doing a single bit of good for me. But then once I am on them it is difficult to get medical professionals to even look at the possibility that they might not be having any kind of effect. Every time I have gone to a psychiatrist and have asked me how I'm doing and I'm in distress about something, they want to change or add to my medication. I get the feeling that I'm just not supposed to feel anything. The truth is that life is not static.
If meds help people, great. I question sometimes who is actually being helped though. Ultimately it is between the doctor(s) and their patient. I was very fortunate that my first regular psychiatrist understood my sensitivity to medication and never forced me to stay on anything, and was more than willing to help me try all kinds of different things and keep an open mind.
