I was on it for 4 years about and stopped in 2005 (just started back on it due to a flare that I couldn't get under control.) The only things I've experienced are risk of infection and my veins are bad. My infusion nurse told me that if you keep starting and stopping Remicade often it loses it affect if you have to need it again. I started back on it cause I've been on everything else. Surgery was my next option and I'm not ready for that yet.
Good luck and I hope you start feeling better soon!
