You may not be the "healthy male" (usually of 70-80 kg) that is the typical subject in studies. If your caffeine half-life is 7 hrs, one of two cups of coffee at 17 h is still in your blood at midnight. Another factor affecting sleep is the color of the light. Reddish hues support sleepiness (think "evolution" and "sunset"), while cold bluish light (daylight) makes it more difficult to fall asleep. Now, most computer screens are set to daylight color temperatures... If you must do computer work before bedtime, set the monitor to a warm, reddish temperature in the last hour. (DarkAdapted is a good tool for that, it even supports scheduling!) The biological half-life of caffeine can be veeery long (depending on other factors, see wikipedia).

You are lacking the basic needs to survival, no wonder you can't be productive in your job, business, etc. One thing i discovered with myself, when I have really productive days, say I am up on my laptop writing a blog post or something to do with my website and I get a lot done or something significant. Even though I may be up till 2 or 3 am, I think great the next day and not tired. The problem may be the kind of productivity we are involved with and maybe that is why we have insomnia and other sleep disorders.
