I definitely know what you mean about not wanting to be on more meds than you have to be. I was on Remicade for about 9 months and it made a world of difference in how I felt, but I wasn't in remission. My GI wanted my colonoscopy to be completely disease-free and it wasn't... but I felt fine, no symptoms at all! I stopped taking the Remicade last October (against GIs advice) because I was having lots of side effects (acne, weight gain, achy knees, etc) and since then I haven't had a flare yet. I haven't had a scope since then so who knows, I may or may not be in remission... I still feel great though, in fact my bloodwork still continues to improve. I'm on pentasa for maintenance but that's it.
If you have antibodies to the Remicade, I wouldn't think that you should take it anymore, because you're risking a reaction... has your doc said anything about switching to Humira? Maybe you could try going without the Remicade for awhile and then start Humira if you start to flare again. Good luck!
