How many book effect can be at a time? If you read increase energy drink effect for 31 days and you read again book increase your stats training gained for the next 31 days. Does both working on stack or one must wait another to finish the CD?
Edit: Really, books can be thought of as a separate type of consumable item with a separate mutually exclusive cooldown of 31 days.
Similar to the way one gains the advantage of Vicodin and some other drugs for the entire duration of the Drug cooldown, you gain the benefit of the book for the entire duration of the cooldown with most books.
Some books, you gain the benefit at the conclusion of the cooldown(i.e. Making Friends, Enemies, and Cakes), so in that way, some of them are a bit different, but the cooldown thing still applies. It's mutually exclusive for all books, and it's always 31 days.
