Let's see, I have three friends that are cocaine addicts, one of them is a junkie. He's lost everything, his long time GF, one of his cars, one of his homes, multiple jobs, and has been arrested for possession a number of times in the last few months. He's waiting to be sentenced. The other two are functional, but I can't stand to be around them.
I have an issue with booze. I'd binge drink when I'd go out, and would drink every day. I wouldn't get wasted, but would definitely not be sober. I could probably count on one hand the number of days I wouldn't drink in a year over the last few years. I went 8 months without drinking anything, had a few last weekend and didn't have any fun with it. It's tough though, I could see myself slipping back into the habit of daily drinking again. It keeps me numb.
