I recently wrote a book called Innessential Pharmacology (Amazon affiliate link). I suggest you buy it. It's good. It's also the number one book on Amazon in the depression and pharmacology categories, beating Michael Pollan’s “How to Change Your Mind.”
This is slightly hilarious to me. Also, based on the number two title, a lot of people need to prep for the pharmacy exam? I want to get into that game. If any of you Medical or Pharmacy students use my book to entertain yourself and you do better on an exam, please let me know.
