from what i heard on the radio today, he's been stuggling with addiction problems for years but has been able to keep it under the radar for the mostpart. according to his friends, he's been having a really hard time of it and whether accidental, or suicide, they aren't all that surprised. also, he'd started taking the ambien while filming batman. his role was deeply disturbing to him and he wasn't able to sleep. one night, he had said he took 2 ambien and still only slept 2 or 3 hours.

at this point, i don't see how anyone can really know what happened. it could've easily gone either way. but they still haven't even named his official cause of death so it could be something completely different. maybe he had some hidden disease that wasn't known to the public. until we know, it's really not fair for anybody to criticize him.
