Interesting story. Did you ever have any substance abuse problems along the way? I am told that substance abusers frequently have gambling problems, and vice versa.
I was definitely an alcoholic, but I never had any gambling problems, even though I like to gamble, and have plans to do more in the future. It never gave me the same sensation that you describe. Last time I posted this I received several PMs telling me I was fooling myself, but I found I was able to engage in one activity (gambling) in moderation, but not the other (drinking). Was that your experience (in reverse)?
