I heard on the news this morning that he was taking Ambien and that it wasn't working very well for him. One of my coworkers just had Lasik and was given an Ambien to take that night, he took it and within minutes was falling asleep in his dinner. His family put him to bed. He doesn't remember anything. So this is complete and total speculation....... but maybe if the Ambien wasn't working well, Heath decided to try taking more than the recommended dosage, and just took too much, or took something else that reacted with it. Again this is just a guess, but I think some people think pills automatically = suicide, and that may not be the case. I hope not.
