How to unlike all your facebook pages likes without stress

TO VIEW ALL PAGES YOU HAVE EVER LIKED

On desktop:

Go to your profile (when you're in "home" view, click your name in the top left corner)

Look at the URL, it should read http://facebook.com/YOURUSERNAME (for example, mine is "nonso.ngene.144")

Now, click on the URL in the tab, DO NOT DELETE ANYTHING, but, at the very end, type in "/likes"

So it should read:
http://facebook.com/YOURUSERNAME/likes

Hit GO (or "ENTER" on your keyboard)
The new page loads and shows with all your page likes..

Start to UNLIKE each one by placing the cursor on the like bar, go down, hit it.

                                                    OR

type "pages I like" into the top search tab, every page you liked will show up and you can go down the list and unlike them!
