The spinach may have worked for you when you were doing better, but now it may just be a little tought to handle until you get more stable. Obviously the spinach isn't working right now. Also, to add more spinach in one sitting is not what you should be trying to do. You want to spread out your IF as much as possible in the day so you don't trigger your stomach too much.
My advice is this: -cut out the spinach -add a few new forms of IF from Heather's cheat sheet list to each and every meal in small quantity -don't count on the Oat Bran & applesauce to be enough IF, it just isn't enough (I'm a D and it doesn't even make me go..) it is good for you so keep it, just add more IF to each meal..
I hope you take the spinach advice, I still have yet to be able to tolerate it and I've been stable for months. Kat
