A good and important list. I would have to say yes to at least of them 10 wrt my parents, now deceased. I myself am very fortunatewrt drink. More than one beer and I'm liable to have a hangover to beat the band. But you know what, addiction is sneaky and can morph into other forms. For me, it's food. My family rarely ate out, maybe 1 dozen times in a year. But those were usually pretty fun times, as opposed to the bland food and hostility usually found at the dinner table. FF to 2005 and I would say I was eating over 200 meals a year at a restaurant (Believe it or not this is about the national average, about 4 times a week.) But I thought about it all the time. I've lost a lot of weight, 200# to 175# in the last year or so, but food is still my Achilles. And I still have a belly that my W rightly criticizes.
Alcohol, and the anxieties that caused it to be abused, directly killed my mom and two uncles, one of whom literally lived on the street. Two cousins committed suicide at 21 in part due to drug addictions. One brother has spent time in prison for possession of drugs. Maybe In should consider my self lucky, but it is a tough battle.
