I've gone for weeks with no more than 2 hours sleep per day (mania) and was constantly drinking beer during my waking hours.
I probably would have really gone nuts without the beer to keep me calmed down.
I don't think it's at all weird that two entertainers have recently died [sic] after a period of sleep disorder.
It would be my guess that bipolar disorder has a higher incidence among entertainers than among the general population and it's certianly the case that risky behavior tends to go hand in hand with manic episodes.
