Hi there,
I have had two infusions of Remicade and am on 100mg Azathioprine also started at roughly the same time.
I find my Crohns is definitely much improved already, but I know it varies hugely. The extent of the disease you have and the amount of treatment/surgery you have had as well as your overall health will all contribute to how well the Remicade works. It doesn't work for everyone but I have been told by every expert I have spoken to (and I have spoken to a few!) that this is the "Gold Standard" of treatments.
I am having my third infusion tomorrow. It is the tiredness and joint pains etc which are now taking over in terms of obsessing me. I have also developed constipation (as opposed to the opposite) and that has been a problem which i am going to talk to my GI nurse about tomorrow.
Lots of luck with your treatment.
