There are a few people in my CCFA support group who have Crohn's Disease, and are treating it with Remicade with very good results. The feedback I hear is that they are a bit fatigued on the days of their infusions (and perhaps for another day or two after), but that after that it works well for them in controlling the symptoms. I also heard the same thing from my friend with CD taking Humira - he calls it a feeling of being "wiped out" right after the infusion. Good luck with it and let us know how it goes.
Mema- based on your posts I think you might benefit from joining the local CCFA support group in your area. With the recent passing of your husband, new diagnosis, new treatment etc., it sounds like you are passing into a new chapter in your life and I really think it will help the transition.
Also- I don't know if you like to watch movies on Netflix but I was very, very impressed by a movie I just saw called "The Fault In Our Stars". It's about 2 17-18 year old kids with terminal cancer who meet in a support group for cancer patients and fall in love. In other words, kids who have a worse prognosis than all of us. When I read about the movie, I wasn't sure I would like it because I am not really into those kinds of films (i.e., tearjerky teen romance). However, I found it was extremely intelligent, well done and well acted, with a fantastic performance by Shailene Woodley as one of the two main characters in the film, who is living out her life with terminal cancer. You might find it to be inspirational.
