Thanks for the reply!

Why are you on modafinil at this point?

To be frank, I suppose just because it makes me feel brisk and sharp, rather than for reasons having to do with wakefulness, or excessive sleepiness, or narcolepsy. (Furthermore, I might as well confess that I was never exactly prescribed modafinil.)

I think you need to talk to your prescriber about your sleep issue.

I know that, in some sense, I really should. But I'm afraid that my prescriber will take me off Parnate, even if the modafinil is to blame. If I want to shift the blame off of the Parnate, I'd have to confess that I've been, uh, independently supplementing my parnate with modafinil.

If you can't tell that your brain is suffering, that is a red flag. So is sleeping on the office floor. Do not ignore this.

I hear you. Today, for the first time, I'm having very apparent cognitive difficulties. I frequently forget what I was doing recently or what I intended to do imminently -- I find myself constantly having to write very simple lists of three or four items, so that I don't forget what I'm supposed to be doing. In previous days, I had felt energetic and sharp enough that I didn't really imagine that my sleep deprivation would accumulate, leading to my mind thrashing on so many different tasks that I end up getting nearly nothing done.

Despite every intention to get a ton of work done today on a paper that's due tomorrow, I've gotten basically nothing done, since I'm constantly switching context, and hardly moving forward.

I'm definitely going to slow down, get some sleep, and give some serious thought about whether modafinil really benefits me at all, given that I've got parnate.

Thanks again.
