mears, only just seen this...
I've been on sulphasalazine for six months now, for a similar condition, and although I can't say that it has made an awful lot of difference to my symptoms, I've had none of the side effects that I was warned about. Been out in the sun with no problems, bloods fine, no stomach upsets. Very "strong" coloured urine though!
Suspect I know the homeopathist you mention (she's a local GP too?), she treated my dd for alopecia (a related condition too) and it didn't make a noticeable difference, though dd loved taking the powders!
Is your dh seeing the local rheumatologist, or perhaps the scary lady at GRI ?
I've found that swimming makes a big difference... not by controlling my symptoms, but I feel fitter, and sleep a lot better if I've had a swim.
AFAIK, the emphasis in the conventional treatment of RA and similar conditions is to get in with the DMARDs before there is any evidence of joint damage on Xrays; it prevents deformities later on in life.
Let me know if I can be of any help.
