I was speaking anecdotally, both from my experiences and the many experiences I've read about online. Modafinil is a great replacement for sleep once in a while, but repeated usage ends up making it useless. It's not that you don't notice the effects, more like you notice the lack of them. Still tired, unable to focus, etc.
