How did you all do it?

Hi im going into the nursing program pretty soon here and I wanted to ask the ones that went through the nursing program working a full time or part time job, how the hell did you do it? I currently work in a dialysis clinic in center and the hours are grueling I personally work 12-15 hours per day and I need to make a change into something that will allow me to go to school and work at the same time. What jobs helped you and what advice can you give me to allow me to work and pay my rent while doing the nursing program its going to be M-Thurs my school schedule.
