Thank you for your response.... what I mean by short life of the drug is that it has only been around since 1998 and has no real long term studies attached to it. I am in my forth month of 6mp and my Crohn's is still very active. My veins are shot out already from the hospitilizations and damage I have done on my own. I am just having a really hard time adjusting to all of this. I can only work part time and finacially I am swallowed with all of the copays and such. Having a hard time. Did you experience?
