I don't think you know what several orders of magnitude means. Did you have an IQ of 10 and then got to 100 or 1000? Anyway, this aside, the feeling that you are few times smarter is there, like I say, it's a high ( which, btw, like any dopamine pumping thing, means your next high needs Moar and moar) . The reality is that you are a bit smarter, not few times more, and you work much more.
