I don't really mind needles too much. I'm a nurse and have given thousands but i guess it's different when it's to yourself.
I have had a quick look at the Avonex section here and i must say it does not sound too positive.
I've heard that rebix is better but according to who? My neurologist suggested Avonex because it's good to use after a CIS and he is able to prescribe it so that i don't have to pay for it. I think he said it's the only one that i can use without having to pay. Othrewise it's $20,000 per year
I have a couple of months to research some more but the drug section on this website is quite frightening to read.
