I'm a white girl with crazy curls, but I'm not sure what protective style will work for me. Ideas?

I have mostly 3B curls but lots of other types of curls (the stylist said I have a mix of curls that she's never seen before) and I'm not really sure what styles I can use to keep my curls protected for several days. I'm usually washing every other day which is time consuming and frustrating. Any ideas? Most protective styles don't seem to work for me. I sleep on a satin pillowcase but the curls always wind up crushed.
