honestly, I dont know why I havent came to one of these before. I have had CD now for going on 10 years. I have avoided surgery for this whole time by doing everything the doc has told me, except I do smoke, which, yes I get griped at every time I go into his office...I have on the other hand gone from 1 1/2 packs to 5 a day. Quitting is right around the corner, just cant seem to give up those last 5. Anyways, I have been on humira for the past 3 years, and it is no longer working, they are wanting me to start cimzia. I asked the pharmacist what the difference was, he was like not much just the amount and how often you have to take it. I am all for once a month shot instead of every other week, but, how long before this does not work? The doctor has basically told me if this does not work, the only option left would be surgery. I am kind of not really sure about surgery, I guess what is meant to be will be. I am thankful, I have God on my side and will be there no matter what happens!!
