Yes!
My food for the longest time was coming out partially digested too - still is sometimes. Hmmmmmmm, and I struggled with a bit of an eating disorder for awhile too. How is it that you have been able to find some peace? (if you don't mind).
So, you used to get a great deal of gas (flatulence) - that is a symptom too. I have found that my stomach is real sensitive, and I have to be real careful what I eat and when, and how much, or I get constipated, the reverse, or lots of gas.
