I'm not Mr. Sulla and I've never argued that anyone who doubts the efficacy of brain medications is a Scientologist!
You're correct in saying that brain medications are not a cure-all, but then neither is aspirin. Just because aspirin doesn't relieve the pain from a broken leg doesn't mean that we should toss aspirin out the door, or even that it's overprescribed. Those who need medications should take them; those who don't, shouldn't.
Sorry for the confusion! :D
