Not me. ;-( Was in remission on Remicade 2 years though and that's worth a lot (for me)!
Also a note... I think it would depend upon how mild your case of Crohn's is. The meds you listed are designed as maintenance meds. The theory being that taking them is required to help. That said, stopping Remicade for long periods of time can build an immunity to the med. Your body can develop antibodies and then it can stop working (or have an adverse reaction). For some people, once the body stops responding to one TNF, others are less effective. Basically, I wouldn't mess with maintenance if something is working.
