Brain meds are just like any other medication. When used judiciously, they save lives. But way too often they get used improperly.
Case in point. (It's on Salon so you'll have to click through an ad to get to the full story; sorry about that.) But that's as much of an autism rant as it is a medicational rant, so I'll leave it as just the link. (Short version of the rant, since I can't keep myself away: I'm autistic. I'm also human. Why do so many neurotypical People In Charge see these two things as incompatible?)
A major problem is that people are expecting meds to do all the work for them, when that's hardly the case. Taking painkillers, antibiotics, etc. after, say, having knee surgery may let you be up and about faster (and reduce the risk to yourself), but if you go skiing three days after the surgery, you're not going to be much better off than you were before the surgery. (True story: my mom's crazy ex-boss did that.)
and re: needles: Never did see the big deal about them. Now, MRIs. You have to sedate me to get me into one of those. Seriously. *shudders* Just so damned loud...
