never meant to imply they should be a lifestyle, just that they can be used effectively in appropriate situations. personally, i think they can be a very good thing, but i also think people should couple them with some form of therapy/self-help/wha-have-you, and try to get back off of them as soon as possible.
thing about meds is this (at least with the SSRI/SSNI, i'm not sure about tricyclics & such) - it's not like they're using some pharma-chemical to change your body, they're actually using your own body chemistry. all those meds do is block/plug up the receptacles for seratonin/norepinephrine, so that those chemicals, which are already present in the body and entirely natural, don't get reabsorbed right away; they stay in your bloodstream longer, thus changing your moods. hell, check this out, quoted from wikipedia:
