good morning adl011,
i have not heard any one in this group say their dr. said not to take pain meds to see how the other meds are going to work. getting a restful night is such a struggle for most of us, and i can't imagine not being able to take my meds for relief.
there are several posts about sleeping....look for a thread that's is listed as "benedryl for sleep". several people speak about the different meds that help them.
plaquenil can take 3-6 months to get the best that it is going to get. the prednisone has (i believe) a quicker response time, and i am not familiar with the other med you are on.
you might want to contact your dr., explain the problems you are having with pain and sleep, and see what he/she wants you to do. sleep is so crucial to the management of this disease. Several of us have tried sleeping med prescriptions, and can't tollerate them. some take tylenol pm and have success, and some take benedryl with success.
good luck, try to find something to help you get needed rest.
