I've read the book (and quit smoking with his other book) but I think he fails to account for the diversity of individual reactions to alcohol as a drug. Some people have an easier time drinking (few problems with addiction, no negative changes to behavior, minimal hangovers) than other people (easily addicted, bad moods/behaviors, disruptive hangovers). It's pretty easy to craft a compelling negative narrative if you're the latter type of drinker. Not so much if you're the former. The same with smoking. I was viscously addicted to smoking and quitting was a living hell. But I've know people who were occasional smokers who decided to stop one day and had no problem doing so.
