I have had that issue come up again lately when my Rheumy decided that since I was taking Humira, I didn't need to continue taking the 6-MP that has kept my UC in remission for most of the last 12 years. I went back on the 6-MP when it was obvious the Humira wasn't helping my UC. Four months later I am still having problems if I eat much in the way of green vegies. I have been forced to stick to mostly meat, eggs, cheese and pasta,rice and potatoes. I keep trying to go NSD but that leaves me nothing to eat except meat, eggs and cheese. I miss my vegies so much. I guess it is time to call GI again. It is so hard to get in to see him. Last time I called he had a 5 month waiting list.
