I'm so happy that you found a doctor who sounds like he's capable of treating your condition.
I have a friend who's been on Remicade for 2 years now to treat her chrohn's and it really has improved her quality of life. She said the infusions aren't that terrible as they play videos for the patients to watch while they're being infused (I guess it takes a few hours).
You're right though it is a very serious drug so I hope that it agrees with you and that it's what you've been hoping for.
