Reverse blinking tips?

I have been trying reverse blinking for a while. So when I do it, I count in my head every 5 seconds and then I open my eyes before closing them. But when I've tried it, I don't start to feel tired at all. Is there something missing when I'm trying it and how long should it be done?

dont overcomplicate things you try to get tired and fall asleep. so i would not count but do it by feeling.
you also could try one of the other 100 relaxation techniques and see if they feel better for you
