Direct Entry NP - work as RN during MSN

Hey Guys! I do not intend to replicate any questions that have already been asked so please feel free to link me to other forums if my question has already been answered...

I just finished up my accelerated BSN at a direct entry BSN/MSN program. This was my second career and I cannot wait to be an FNP! That said, I strongly value the RN experience and am hoping to work as an RN during the NP portion. I am hesitant to take time off all-together because I would feel that I am straying from my ultimate career goals. I like the idea of working as an RN because when I finish the NP I would have a solid 2 years of RN experience under my belt. I have been offered nights, 3 12s at a hospital and been promised to have the night before my classes off. The orientation schedule works out perfectly with my schooling. One other note is that I do not have kids.

I know many people say they drop down to part time work when the clinical course load gets heavy but as a new grad, Im not sure I can ask for much more than Ive already been given until Ive been there at least one year. :) As for going part-time to school, my program has us enrolled at half-time (usually 6-8 credits for the entire program). Within the first year the most clinical hours I would do in one semester is 120. In the second year it gets heavy with clinicals at 360/semester (at which point I *think* I would have been at my job long enough to cut back). I also learned that part-time at my school is taking entire semesters off rather than taking fewer credit hours because of when classes are offered.

Im wondering, is it truly feasible to work full time and go to school? I am a motivated worker and OK with the idea of not having the strongest social life for a temporary period of time. I do expect it to be hard, but is it truly impossible/miserable?

* Please note, I posted a separate thread on this because as a NEW nurse, I didn't think I would have the flexibility that those who had been working as RNs for years have at their jobs. I am interested in hearing any and all personal experience regarding working and FNP school!
