when I was in my worst major depression I used to do this with seroquel from time to time. I was nocturnal then, but sometimes when I woke up in the evening, usually after something like 14 hours sleep, I would just pop a seroquel with the hopes of avoiding reality some more. but when I'm hypo-manic, I do the reverse, taking stimulants (or even coffee, or even nothing at all) to stay up for unnatural amounts of time until I feel the effects of sleep deprivation. in some ways, this is also a form of escapism.
