Sounds like trying the Plaquenil is a good idea. While it can take up to 6 months to affect an improvement, it is usually well-tolerated and does inhibit Lupus progress. Most of it find long-term use very helpful in controlling the intensity of the disease.
However, there are other meds that are more proactive in calming your symptoms, and that will work faster, such as prednisone. Or more serious options, such as Imuran, Cellcept, MTX -- Lupus is so mysterious, different meds work for different people.
I have to say that when I get a cold I feel like I've got a cold! I've always figured other symptoms were lessened only in perception -- ie I was so focused on trying to breathe that the regular lupus symptoms just faded into the background.
Hope you feel better soon,
