Hi Ellie
Welcome to the club of anti-tnf users. I understand your apprehension as I felt exactly the same, it seems so daunting to pump our bodies full of these drugs.
However I can give you a positive outcome as I have been using Enbrel since January along with Methotrexate 20mg and it has transformed my life. I still have occasional flares and fatigue still seems to be a problem if I overdo things but on a day to day basis my life has turned around.
I have had no side effects from Enbrel apart from the occasional bruising on the injection site, which I think is probably down to my technique!
I know that everyone is not so successful but I would certainly encourage you to have a go.
Best Wishes
Sue
