I agree that you should be taking more SFS. I have been getting toward C lately as if I am aging and heading that way and I upped my acacia to two heaping tablespoons or more. It definitely helps.
Now you see what I mean about the need for IF. People are too scared of it and now you see your greater need of it. I still don't think you should use an IF grain alone like just oat bran. I prefer to have instant oats with nuts and dried fruit for more IF. Maybe you could try that.
-------------------- IBS-A for 20 years with terrible bloating and gas. On the diet since April 2004. Remember this from Heather's information pages:
"You absolutely must eat insoluble fiber foods, and as much as safely possible, but within the IBS dietary guidelines. Treat insoluble fiber foods with suitable caution, and you'll be able to enjoy a wide variety of them, in very healthy quantities, without problem." Please eat IF foods!
