Hey, Zen. I read that article about your friend. I'm really sorry. That's just unthinkable. I agree with you, though, pouring a depressant on top of natural grieving can amplify the emotion.
I guess it really comes down to whether or not alcohol is making problems for you. Would your life be better without it? Pros and cons. Personally, as much as I thought I enjoyed drinking there aren't really any "pros" for me. I could think of plenty of excuses, but no actual good reasons.
Something to consider is that people who do not have a drinking problem don't feel at odds with themselves about drinking. They do or they don't and that's that.
Anyway, glad you're reading the book. Great read.
