My dad is an alcoholic and I’m convinced that I’ve inherited certain vulnerabilities to addiction. I’ve never had a problem with alcohol, but by God, when I get into a regular full-caf coffee habit, and then I miss one or two cups, the withdrawal symptoms hit me hard. I’ve been trying to slowly lower my ratio, but it’s hard to even contemplate going totally decaf when I’ve got a retail job and I’m a little scared of trying to deal with customers and withdrawal headaches at the same time.
