I've always shared a fairly deep connection with Mr. Bourdain for two reason...number one, I actually look enough like him that when I travel I am constantly being asked if I am him, or do I know that I look like him etc...
The second is that we were both functional heroin addicts for some part of our professional lives.
His tell-all book "Kitchen Confidential" hit home to me like a 20-oz T-bone and a good bottle of red. His unafraid discussions of his addictions were a breath of fresh air in the otherwise stultified environment of talking-about-work.
There is little doubt in my mind that his struggles with addiction are related to the suicide, at some perhaps never to be known level.
He entertained the shit outta me, so he will be missed...cheers to you Anthony we hardly knew you.
