I've only just installed it, and found that I need to disable it if I'm doing any serious work. However if I have some free time at night to go over pinned tabs or read some articles I leave it on and find I do get sleepier much faster, to the detriment of my open-tab count.

Is serious work == Photoshop or does it bother you when programming too? I only tolerate f.lux when programming, but it happens to be what I do every night :)

I can program for 30 minutes with it, but I get tired :) so if I am troubleshooting a problem that is going to take a while or a client indicates it is urgent, f.lux goes off.
