Jocelyn,
My experience has been almost exactly the same as Don' s. Only difference is that I started on Humira then switched to Enbril. I have had RA for more than 10 yrs. I am almost 54. On Labor Day I ran a mile in a "fun run" and I do zumba regularly. I have grandkids I chase after too. Before biologics I could barely walk and horrific pain in knees and ankles. I even had to have some surgery to get rid of damage done prior to humira. The only negative is that there are so many people like us that can't get these meds, for one reason or another.
Btw, I still don't like giving myself shots, and humira is twice a month instead of weekly, so that is a plus. You get used to it, but you don't have to like it!
