Welcome to the forum, you've found a great place where others know exactly what you're going through. It's a great place to vent and ask advice, and it does become addicting!
The Plaquenil has always bothered my stomach. There are days even if I eat a big meal that it will bother my stomach. The one thing that has helped me tremendously is taking generic Pepcid when I take my Plaquenil. I can even take the Plaquenil without eating any food when I take the Pepcid (though I try not to do that too often). My rheumy has approved me taking the Pepcid with my Plaquenil and I've also checked with my pharmacist and he also says it's okay to take with the Plaquenil.
The fatigue is horrible and it does get very frustrating not having the energy I need to keep my house as clean as I would like, keep up with my laundry and cook, besides wanting to do the fun things. I've learned that I have to pace myself. If today I have to do errands or do a doctors appointment, shopping etc, I won't cook. I'll either pick up a no brainer meal or it's a day we'll hit the restaurants. With having children you're going to have that added extra job you're going to have to save energy for. I honestly don't know if we ever get use to the fatigue. It can be very discouraging at times.
Best thing you can do for yourself is read the Spoon Theory that one of the others recommended and remind yourself that you are not Wonder Woman and you have to pace yourself.
I've also learned to make my appointments (hair, dr, dentist, etc) later in the day so I can still sleep a little longer if I want to. Though that probably isn't an option for you with little ones.
