I wonder if Leflunomide would be an option for you? I "failed" on Sulph and Mtx, then on Mtx and Plaquenil together, and eventually we had a go at Leflu with Plaquenil.
Apart from other non-related problems, I seem to be doing better on this cocktail than anything else; just as well as I am not ever going to charm my grumpy old consultant to even consider anti-TNF's, he did all the DAS, and although I scored WELL over the baseline, refused to even think about them.....but it was the end of the financial year!!!
Anyway, I hope you have Good luck with finding something that is effective for you, Love Lxx
Always be aware that what you do might hurt others........and if it could, do nothing without careful consideration of the consequences
