What a good nickname for "Nolan"?

My name is Nolan Cowan. I don't really have a problem with my name, but everytime I introduce myself to someone I have to repeat my first name a million times. They always say " what? Noah? Nolam? Nola?" it just gets old. Although I hate it when people give themselves nicknames, I'm afraid I'm going to have too so I don't have to repeat my name a million times. I kinda like Axl because I love guns n roses and people tell me al the time that I remind them of Axl from the middle. I also like Cr�e and Duff.
