Login required Sometimes, medscape will bypass the login if you access an article VIA a search engine... Can we get the name of the article/author/date?
(minus the "originally posted by jessica") into your preferred search engine (meaning google, because GOOGLE FTW), and click on the link mentioned above. For some reason, Google searches bypass medscape.com's membership screens. I'd copypasta the whole article here, but I fear that'd open up a can of legal whoop-ass.
You know... for people who are still undiagnosed I wonder why doctors don't administer nicotine for a week or so and see how it affects them. That should give you a diagnosis no?
