Yeah, that would be taking it too far ;-).

I'm not advocating putting yourself into net-loss situations like intentionally getting drunk to practice, but if you happen to find yourself in a state (like in a dream or having a high fever) that presents special challenges and there are no negative consequences to practicing rationality, I think it would be good to do so. When it's easy to do in a dream or with a fever, it will be effortless in real life under "normal" circumstances.
