Reading too much?

Ok, I'll admit it! All I want to do lately is read. Read, Read, and Read some more!!
Honestly I've been racking my brain on "Why I need to read today" or "Why I shouldn't read today?" And it is not even one specific book! I have so many that I want to read at once, but for some reason my mind keeps telling me to finish the book I am reading now before starting another one. Are you able to read multiple books? If so please tell me how you do this. I really want/need to know.
