NP prescribing in CA

I know this is frowned upon but I have heard MDs can self -prescribe or to family members in emergency based cases. I'm a new NP in CA and am too sick to go to urgent care of which my nearest one is far away. Is it illegal for an ACNP to self-prescribe antibiotics? Do I need a cosigner?  Not sure how this works.

It is legal to prescribe non-controlled substances for yourself or family.  Who is going to "frown" on it?  No one.
