peri...what you are saying, as I see it, is the going is at last good and you want to keep it that way.
I kow of no sure way of doing that peri other than emigrating to warmer climes............a monumental decision I realise.
I must just readjust my comment on hormones, as you mentioned pregnancy, I assumed that you were referring to to female sex hormones, which I feel have no part to play in RA, but steroids of course are hormones and they play a vital role in RA.
