Thanks Pat and Joanmarie for your support. The med is a chemotherapy drug, my mg relapse has lasted 6 months now and we've tried ivig, increase in steroids (4omg), retuximab infusion and intense plasma exchange which is still on going. I take azathioprine as well as mestinon 4/5 daily. I just want my life back to my normality but if I take thie med (apparently very good success rate) I risk infertility and thats not something I want to think about. I've heard about the anti c5 trials and I'm hoping they're a sucess but I'll keep my chin up. You need to fight quite a few battles before you win the war as they say.
