In my family, addiction is a gene thing. I have to be carefull with Alcohol, Drugs, Gambling otherwise I'm skrewed. Of the three the only thing I never did is Gamble, I don't see the possible pleasures of it. Drugs----> Way too good so I avoid them
Alcohol----> I grew over it, feeling like a trainwreck every day is not the way to go.
Sex I don't count as long it is not affecting me or others close to me in an unhealthy way.
