Is any pharma company working on an eugeroic with a shorter half-life than modafinil?

e.g. 6 hours instead of 12

as someone with narcolepsy who has done multiple clinical trials: unlikely to come to market via FDA approval and trials unless the military has a specific use case OR massive influx in developing better supports for nightshift workers.

Because of the cost of trials, it's usually weighed against potential profit. There have been meds I was really looking forward to trying that didn't make it to market. And then sometimes aren't available in various countries: armodafanil wasn't brought to market in Canada for the longest time; zopiclone (sleeping pill, similar to zolpidem / Ambien, but different feel) generally doesn't seem to be available in the USA.

And that generally the goal is developing longer acting, rather than shorter duration. 

But I can absolutely understand the "okay, brain has had enough focused alertness, can we just have this taper off until I want that level of functioning again"
