With all due respect, I've heard the exact same thing from a number of folks taking Opioids after surgery. They were right, fortunately, and navigated their withdrawal symptoms without incident.

I'm sure you're right too, but it's not a particularly convincing argument. I've definitely seen behaviors that horrify me from some of the caffeine addicts in my life.
