Hi there, you certainly have some health challenges!
Why take immune suppressant drugs, many side-effects occur as a consequence and you will be battling the R.Arthritis in addition to the many and countless side-effects. Go and see a decent naturopathic doc and get off those ridiculous drugs.
I have treated dozens of RA patients myself and seen them take all manner of drugs like steroids, anti-inflams, chemotherapy drugs and immune suppressants. Maybe my R.A page can give you a few good hints and tips:
Your liver is a big immune organ, by suppressing immunity you will find it almost impossible to recover from many illnesses. Hep C can be treated very well by visiting a good herbalist. I have read about many clinical trials in both Australia and in Europe which have shown excellent promise with the use of herbs instead of immunosuppressives and other drugs.
