If you want the "full story", with peer-reviewed sources, about SSRIs, including a true/false on the various assertions that get passed around the Internet often with little justification, I strongly recommend http://slatestarcodex.com/2014/07/07/ssris-much-more-than-yo.... Scott is both a licensed psychiatrist and a very good rationalist with access to a lot of good data, who doesn't easily fall for Internet misinformation and definitely doesn't gloss over the "complicated bits" about the flaws and methodologies in clinical trials. This post is my go-to source for most discussions about SSRIs.
