Help to change positions or not?

Hi, I am having a hard time trying to decide if I should change positions or not. One job is in an outpatient area of the same hospital with daytime hours, 4 days a week and 1 weekend on call a month. The other is in an intensive care unit on nocs 5 - 12 hours shifts pay period but that includes every other weekend. And of course all the holidays. The ICU area positives are the differential, I already know the job, I would be there less, 5 times rather than 8 times a pay period. However, it is playing a toll on my health and it is high stress. Managment is not good, unflexible staffing, but GREAT coworkers. The other outpatient area the manager is great, it's an acutal outpatient hospital job, not a clinic job, won't lose seniority or have to change benefits, but no shift differential (loss of about $5.00 and hour) and would be less stress once I learned the job. I have children, who are busy. I am worried if I take the outpatient job, I won't have several consecutive days off, it would be harder to go eat lunch with my kids at school, and do those things that are fun because I would have to be at work. The ICU position along with the differential has potential to pick up extra hours/overtime whenever I want. The outpatient area, I already shadowed for a day, the manager is after me (very flattering), and I tend to believe that it would be a less hostile place to work in. And for those of you that work nocs (I've been doing it 5 plus years), you know some of that time that I am home I am sleeping anyway or napping. I dread the nocs that I have to go in because it's always hanging over my head that you still have to go to work. A lot of my kids activities are later in the afternoon and every weekend. So every other weekend i lose all day Sunday to sleep. And usually can't spend the whole day on Saturday with them. Plus summer is coming (I don't need a babysitter, but want them to stay busy), but during the school year they are in school anyway so I wouldn't feel guilty, except I may not be able to go on that last minute field trip unless I have it planned in the schedule ahead of time. I feel guilty when I'm sleeping (therefore I do not get much) and I feel guilty working. However, I have a GREAT DH. I don't know if I went there and asked her for a pay increase to help match what I am making or if it's just if you were hired into the system as a new employee that you can negotiate. Any thoughts as far as helping me see the pros and cons? I really don't know what to do. The $ is partially a reason to stay, but I could make it with out it.
