First of all, love, love, love your Boston! I had my little girl, Shamrock, also a Boston, who got very sick at 11 years old, and had to be put to sleep. They are the best.
I started Simponi for one month, and then the insurance company denied me, because I hadn't tried Enbrel or Humira, just Remicade. I asked why they approved the one shot? They said it was just a courtesy. Well, I wish I could try it a little longer; that injection was a breeze compared to Enbrel!!!
