>it can be very hard for someone who is cognitively compromised to make an objectively good choice
Accepting ones own personal responsibility is a requirement for a healthy mental condition; leaving the responsibility for ones mental health to other agencies and denying ones own agency - well, this is the very definition of mentally un-well.
Educate yourself before you fall into this scenario, is what I'm saying. Sure, if you're so mentally un-well that you can't care for yourself, you're going to need help - but too many times, that help turns to betrayal when one problem (mental illness) gets supplanted with another (pharmaceutical addiction).
There are no silver bullets to mental illness - not even the ones that come in a nicely packaged pill container.
We do not have the handle on mental illness that we think we do.
So no, just assuming "because everyone else is doing it" is not a good enough reason, imho, to put oneself in the position of addiction to pharmaceutical products. Take personal responsibility, and consider the alternatives before one becomes pharmaceutically dependent in order to maintain a 'healthy life'. This is a mine-field, and is by no means a settled issue in our current culture.
