Methotrexate to Enbrel

So after moving up to methotrexate injects for the past month - they did not slow down the arthritis at all. So in a few weeks I will begin my first biologic - Enbrel. Awaiting my final TB test and chest X-ray. I have mixed feelings about this - I have been awaiting this change for along time. My hope is that by the summer I will be mobile. Bike rides with the kids and playing on the beach. I want to be active and not worry that one busy day is going to send me to the couch for three. I know there are other Moms with RA and PsA out there. How did you feel about moving onto a biologic? How quickly did you see results?
