Here were my GI's recommendations for constipation - they may or may not be EFI-friendly but I think for the most part they are - assuming you are not fructose-sensitive 1. 1 citrus fruit per day (1 orange or 1/2 grapefruit) 2. 5-6 pieces dried fruit per day (dried pears, nectaries, figs, prunes, apricots) 3. 1 tbsp Benefiber twice a day (sounds like you have this covered with the acacia) 4. 8 glasses water per day 5. 1 glass PlumSmart juice at bedtime (very yummy, and contains probiotics) These seemed to help me. I also find that sitting on the toilet with my feet propped on a stool and my thighs pressing into my abdomen helps stimulate my colon.
I also took Amitiza for a month, you might find that helpful as well.
