I think that actually represents one of the central problems with psychoactive drugs is you can think that they're helping you, but that's very different from them helping you. And I think that's actually one of the most important reasons to try to use them as infrequently as possible—it will aid that self-assessment because if you're constantly in the throes of it, you can easily lose track of who you are and how you relate to who you used to be and where you're going.
