Does facebook allow you to change your alternate name multiple times?

I know FB limits that amount of times you change your name, but I want to know if that applies to alternate/nicknames (The name that is right beside your real one).

Ex. I'm Alexander Brown. On FB that's the name you'll find. I have many nicknames like Alex, Al, Brownie etc. I like to change my nickname a lot, so how many times can I change it? Are they limited or unlimited?

There is no limit to change your nickname dear..you can change any time as you want.
