Welcome, Broken Dishwasher, to Healing Well!
I have to agree with Melissa, it would be highly unusual to experience these side effects from Plaquenil... very, very unlikely. It is however, very possible that you are feeling sadness/depression from the diagnosis and from starting treatment for Lupus. It happens on an unconscious
level, so you may not even be aware of what is happening.
You mention you are taking "another drug" with these same side effects. What medication is that? Even if you have been taking whatever-this-is for a while, it is possible that adding Plaquenil has accentuated side effects.
Hang in there,
