Working while doing accelerated nursing program

I was just wondering if anyone worked the weekend while doing an accelerated nursing program? I am thinking about still working my friday and saturday waitressing shifts at least through the summer. I have already taken pharmacology which everyone else in my cohort will be taking as well as the NURS301 class. So only 7 credits instead of 10. Has anyone had experience working and going to school ? Just nervous and wondering how big the load was. My undergrad degree was Human Biology so my classes were pretty intense, I am hoping that with that expierance I can still manage !
