I think you've got the wrong approach. Sleep is a waste of time! If you can't sleep count your blessings and do something productive.

I sometimes get severe insomnia. After the third day, the most productive thing I could do is menace in a deranged and hallucinatory fashion anybody who dares hand out this kind of advice.

I've always had what you might call severe insomnia. I rarely sleep for more than four hours, and I've found I do pretty well on two. As far as I know I've never slept eight without either being up 2-3 nights beforehand or being very, horribly drunk. In my experience if you are not sleeping, staying in bed will just make you more tired. It is better to embrace it, get up and do something. So that's where I'm coming from, I'm sorry if it caused offence.

Three days/two nights without sleeping, as in without going to bed at all, should not cause you to hallucinate. That's just a weekend. That's as uncommon as you might think. If you are hallucinating there might be something else going on.
