Azathioprine
"Doctor put me on azathioprine because I got sick from taking methotrexate for my rheumatoid arthritis.  Good news is it didn't make me sick and I had no noticeable side effects / Bad news is it didn't make pain/stiffness any better than taking nothing at all.  Now going to try injectable methotrexate to see if that will work without the nausea/stomach side effects?"
