Will you have help from family? I know that her mother and mother-in-law would take turns coming at night those first 3-4 months. They would take care of the babies so she could sleep a good 8 hours at night. It makes a big difference! She was on her own during the day while her husband was at work but said it wasn't too bad since she was able to sleep at night.
My husband and I were on our own at night and I was alone throughout the day as well. If you think you know what sleep deprivation is, you have no idea until you've had multiples. We eventually were able to work out a system but I think we were both pretty much zombies the first 3-4 months.
I wish I had found this site before having my babies. It would have helped me out a lot. Good luck with your pregnancy!
