Hey Dan,
I'm also on Enbrel. I was on the placebo during the first six months of the study. I'm on week 8 of the real thing! I'm sleeping like a baby! I still have some pain but compared to my usual pain and stiffness during our winter rains...I feel great. I've had frequent injection site reactions. 2" diameter raised red welts, occasionally bruised but not painful. I inject myself and it was very easy to get used to, I sometimes give my kids a thrill and let them "shoot" me.
Hope it works beautifully for you.
Take care,
Kirst
