I'm about to launch into NS myself and have alot on my plate. Between work, classes, commute, studying, and clinicals, I figure I'm looking at about 100 hours per week...which doesnt leave alot of time to sleep and visit with family.
Thankfully...my mother is taking on a primary helper role with regards to helping with kids, meals, shopping etc. My husband will do alot of it and I'll chip in where I can...but without her assistance, we'd have no consistent oversight for them when they are out of school and we're still working (or in class).... and the combination of work, extracurricular activity schedule, laundry, housework, yardwork, meals, grocery shopping etc is alot for any one person. I cant tell you how much her assistance will help on all fronts.
Having said that...I'm still nervous about getting through it and doing well...so as far as my husband and boss are concerned...my schedule on mon/tues/wed is 8am to 4pm. Any time not in class will be used for studying during those hours at the school. Clinical hours will vary... so that will be what it is...but I can gaurantee you that those shifts will be 2 hours longer than reality to accomodate some extra studying on those days as well. My NS schedule, as far as I'm concerned, needs to include some set in stone study time and I can add to that wherever and whenever possible...but, like classes...some of it is not arbitrary if I'm to succeed...and I refuse to act as if it is.
I know my family...I've been married for over 12 years and know the dynamics of my husband and kids....and studying away from home and/or at night when all are asleep is my best option...because the 'mommy's studying/working' thing isnt sufficient to keep anyone at bay from disturbing me (read minimize quality of study time) with all the little items in day-to-day life.
Bottom line...I agree with those who say to get out and study elsewhere whenever possible, because it's the only way to have a definitive separation between work (which NS is)...and home.
