How long to wait?

I was diagnosed over a year ago with RA. After waiting forever and a day to get an appointment with a rheumatologist, I was put on plaquenil about 5 months ago. It has done absolutely nothing for me, and my rheumatologist keeps saying "give it time".  I know it can take some time to work, but how long does one wait and suffer before trying something else? 

My pain levels have increased significantly over the past few months, and some days my knees and feet hurt so badly that I can hardly walk.  My fatigue level is a real problem as well, probably due to the RA and chronic anemia I seem to suffer from.

I apologize that my very first post is a gripe, but I'm growing impatient and would like some relief.  I'm too young to feel this old!
