Thanks for the advice. I had a quick look at the Fumaderm on tinternet and to be honest, I am very wary of taking any form oral drugs with side effects as I really feel that having been a scabby cow for the last 30 years nearly, I would rather stay scabby than put my health at risk.
I am maybe naively going to to stick to the cow treatment and give that Udder stuff a go though as I really do not see what harm that will do!!

If i come back in a few weeks saying nothing but MOOOOOOOO then maybe that will be the side effect!!

Thanks for the great advice and good luck to those who are on the Mtx, cylo and such like.
