For me the plaquenil kicked in at 3-4 months, for some it takes longer. Each and every person is different.
If you have another appointment scheduled, make a list of all your questions - if you can, make 2 copies, one you can read from and take notes on, and one to give the doc. It is such a help - for our foggy minds to have it written down is such a help! I've gone in with as many as 25 questions at a time - - I had one rheumy early on who just brushed me off and ignored the questions. I only saw him once and went to a different one. You deserve to be seen, to be listened to, and to have your questions answered as best as they can be answered.
Many of the others here will chime in soon, and give you more support as well,
