I'm not one to necessarily believe the people with experience over a doctor who reads out of a book, but I really want to know which book says quitting cold turkey causes more harm than good. And yeah, what good is seeking a medical opinion from a doctor if you can't understand what he's saying? Something sounds a little fishy to me. But whatever, he's just some kid.
I also love the fact that we have a forum here of people (some are really knowledgeable) and a whole internet of information that we can use to double check the opinion of a physician.
